Shenzhen Mingjiada Electronics Co., Ltd. supplies and recycles the Infineon IPP60R180P7 high-efficiency CoolMOS™ P7 power MOSFET.

I. IPP60R180P7 Product Overview

The IPP60R180P7 is a 600V high-voltage N-channel power MOSFET developed by Infineon based on the seventh-generation Super Junction CoolMOS™ P7 technology. As an upgraded successor to the previous-generation P6 series, this device strikes a perfect balance between ultra-high conversion efficiency, excellent operational stability and ease of design integration, making it a core power device for industrial-grade high-voltage power conversion applications. The device utilises a proven Super Junction (SJ) process architecture, building on the advantages of Infineon’s CoolMOS™ technology, which has been iteratively optimised since 1998. Through process innovations, it significantly reduces conduction and switching losses whilst enhancing the device’s robustness and immunity to interference, making it fully compatible with a wide range of mainstream power supply topologies, including hard-switching and resonant switching.

The IPP60R180P7 is housed in a TO-252 surface-mount package, offering the advantage of a compact footprint whilst balancing thermal management performance with integrated design requirements. Strictly adhering to JEDEC industrial-grade certification standards, it ensures long-term stable operation under complex industrial conditions and is widely applicable to high-voltage power conversion scenarios across multiple sectors, including consumer electronics, industrial equipment and power supplies for new energy systems.

II. Core Technical Architecture of the IPP60R180P7

The IPP60R180P7 incorporates CoolMOS™ P7 seventh-generation super-junction technology, a breakthrough process solution in the field of high-voltage power MOSFETs, representing a comprehensive upgrade over traditional MOSFETs and the previous-generation P6 series. Its core technical advantage lies in the optimised super-junction vertical structure, which significantly reduces the on-resistance per unit area of the device, achieving an excellent RDS(on)·A figure of merit of less than 1 Ω·mm². This enables both lower on-resistance losses and higher power density within the same package size.

At the same time, P7 technology has undergone in-depth optimisation of gate charge characteristics. Compared with the P6 series, the total gate charge (Qg) has been reduced by 30 per cent, with a key reduction in the gate-drain charge (QGD) corresponding to the Miller plateau, effectively shortening the switching transition time and reducing switching drive losses and cross-coupling losses at source. The device incorporates an integrated gate resistor, eliminating the need for additional external damping components. This effectively suppresses switching oscillations and reduces electromagnetic interference, whilst simplifying peripheral circuit design and improving the efficiency of solution implementation. Furthermore, the technologically optimised body diode offers exceptional commutation robustness, significantly enhancing the device’s operational stability during topology switching and sudden load changes.

III. Key Electrical Parameters of the IPP60R180P7

Thanks to its precise parameter tuning, the IPP60R180P7 is suitable for medium- and high-voltage, small-to-medium-power power conversion applications. Its core rated parameters and electrical characteristics are as follows; all parameters have been verified through industrial-grade standardised testing:

- Rated voltage (VDS): 600 V; suitable for consumer and general industrial high-voltage busbar applications, with sufficient voltage margin to withstand disturbances such as mains fluctuations and spike pulses

- On-resistance (RDS(on)): Typical value of 180 mΩ; the extremely low on-resistance significantly reduces steady-state conduction losses, effectively minimising device heating and enhancing power supply conversion efficiency at full load

- Rated drain current (ID): 18 A; ample current-carrying capacity to meet the requirements of small-to-medium-power power supplies operating at full load and under short-term overload conditions

- Gate charge characteristics: Low total gate charge (Qg) and low gate-drain charge (QGD), whilst the stored energy in COSS is significantly reduced, markedly optimising switching efficiency under light-load and high-frequency operating conditions

- ESD protection rating: Electrostatic discharge withstand voltage > 2 kV under the Human Body Model (HBM) test, offering excellent electrostatic immunity and effectively mitigating the risk of electrostatic damage during production, assembly and operation and maintenance

- Operating temperature range: Standard industrial-grade temperature range, capable of stable operation across a wide temperature range of -55°C to 150°C, suitable for harsh industrial and outdoor environments

IV. Key Performance Advantages of the IPP60R180P7

1. Extremely low losses, high efficiency and energy savings across all operating conditions

The IPP60R180P7 simultaneously optimises on-resistance and switching losses to achieve high-efficiency operation across the entire load range. Its low RDS(on) characteristics significantly reduce power loss when the device is in the on-state, addressing issues of excessive heat generation and low efficiency under full-load conditions; optimised gate charge and output capacitance characteristics substantially reduce dynamic losses during high-frequency switching, particularly enhancing conversion efficiency under light-load conditions, perfectly meeting current industry demands for power supply energy efficiency upgrades and low-power standby modes. Compared with competing products of the same specification, its excellent RDS(on)·A quality factor enables a smaller device size at the same power rating, facilitating miniaturisation and high-power-density designs.

2. Strong Topology Adaptability, Suitable for Both Hard and Soft Switching

Thanks to its excellent commutation robustness and body diode withstand capability, this device is suitable for both hard-switching topologies and resonant soft-switching topologies. In hard-switching circuits such as PFC boost and flyback converters, it reliably suppresses switching spikes and oscillations, thereby reducing electromagnetic interference; in soft-switching topologies such as LLC resonant converters, the excellent commutation performance of the body diode effectively prevents device damage caused by reverse recovery failure, significantly enhancing the overall reliability of the power supply. A single device can accommodate multiple power supply architectures, reducing component selection and inventory costs.

3. High robustness, suitable for demanding industrial environments

The device has passed full JEDEC industrial-grade certification and undergone rigorous high- and low-temperature cycling, damp heat and voltage surge tests, demonstrating exceptional adaptability to operating conditions. With ESD protection capability exceeding 2 kV, it effectively withstands electrostatic discharges during production, assembly and use, thereby reducing product defect rates; The built-in gate resistor design eliminates the need for additional damping resistors, not only simplifying the peripheral circuitry but also effectively suppressing high-frequency switching oscillations, reducing electromagnetic interference and device voltage stress, and enhancing the overall EMC performance and operational stability of the system.

4. User-friendly design for rapid mass production

The CoolMOS™ P7 series is optimised for ease of use, offering high parameter consistency and fault tolerance, enabling optimal operating conditions without the need for complex driver parameter tuning. The compact TO-252 surface-mount package is compatible with SMT automated mass production processes, balancing thermal performance with layout flexibility. This effectively shortens the R&D cycle for power supply solutions and meets the demands of large-scale mass production.
