Shenzhen Mingjiada Electronics Co., Ltd. offers in-stock supply of Infineon’s CoolMOS™ P7 series N-channel power MOSFETs. Based on 7th-generation super-junction (SJ) technology, this series provides an ideal solution that combines high efficiency and ease of use for applications such as switching power supplies (SMPS), fast-charging adapters, LED drivers, and industrial auxiliary power supplies.
Product Overview
CoolMOS™ P7 is a series of high-voltage super-junction MOSFETs introduced by Infineon for the low-power switching power supply market. It covers voltage ratings of 600V, 700V, 800V, and 950V, and offers a variety of packaging options ranging from SOT-223 surface-mount to TO-220 through-hole packages. This series performs exceptionally well in flyback topologies and PFC circuits, making it the preferred choice for consumer electronics and industrial power supply designs.
Key Technical Advantages
Outstanding Energy Efficiency
In typical flyback applications, the P7 series achieves efficiency gains of up to 3.9% compared to previous-generation products and competitors, while reducing MOSFET temperature by 2°C to 10°C. This advantage stems from significant optimizations of key parameters:
Gate charge (Qg) reduced by 30–60%, significantly lowering drive losses
Output capacitance energy storage (Eoss) reduced by over 50%, effectively reducing switching losses
On-resistance (RDS(on)) as low as 60 mΩ (IPA60R060P7), reducing conduction losses
Balancing Ease of Use and Reliability
While pursuing high efficiency, the P7 series fully addresses design engineers’ needs for “ease of use”:
Optimized gate threshold voltage (Vgs(th) ≈ 3.5 V) and minimal tolerance simplify drive design
Integrated Zener diode ESD protection (HBM rating > 2 kV) improves production yield
Robust body diode capable of withstanding hard switching, suitable for PFC and LLC hybrid topologies
Flexible Package Options
SOT-223: Cost-optimized, direct replacement for DPAK, similar thermal performance, for cost-sensitive consumer power supplies
DPAK: Surface-mount, suitable for high-density designs, industrial SMPS, lighting
TO-220/TO-220FP: Through-hole package, excellent thermal performance, adapters, chargers, audio SMPS
Typical Applications
1. Consumer fast-charging adapters and chargers (10W–75W)
The 700V CoolMOS™ P7 is specifically optimized for flyback topologies such as mobile phone fast chargers and laptop adapters. It supports high-frequency designs (>100 kHz), enabling miniaturization and high power density.
2. LED Lighting and Smart Meters
The 950V P7 devices meet the stringent requirements of industrial applications—such as lighting and smart meters—for wide input voltage ranges and high reliability, reducing switching losses by up to 58% compared to previous generations .
3. Switching Power Supplies (SMPS) and Auxiliary Power Supplies
The 600V/800V P7 series is widely used in TV power supplies, PC power supplies, industrial SMPS, and AUX auxiliary power supplies. It operates stably in both PFC and LLC stages, balancing efficiency with design convenience.
4. Audio SMPS and Server Power Supplies
Low switching losses and low EMI characteristics make the P7 an ideal choice for noise-sensitive applications such as audio amplifier power supplies and server auxiliary power supplies.
