Technical Advantages

Low On-State Loss and Positive Temperature Coefficient: The V_CE(sat) of the IKW25N120T2 exhibits a positive temperature coefficient, facilitating current sharing when multiple devices are connected in parallel and reducing the risk of thermal runaway. The typical saturation voltage drop at 25°C is only 1.7V, effectively reducing power loss in the on-state.

Integrated Soft-Recovery Diode: The built-in EmCon HE diode features soft recovery characteristics and a reverse recovery time of 195 ns, effectively suppressing voltage spikes and electromagnetic interference (EMI) during inverter commutation, thereby enhancing system electromagnetic compatibility.

High Short-Circuit Withstand Capability: A short-circuit withstand time of 10 μs provides the device with greater robustness under abnormal operating conditions, allowing protection circuits sufficient response time. This makes it suitable for applications with high reliability requirements, such as industrial drives and UPS systems.

Low EMI and Easy Parallel Operation: Second-generation TrenchStop® technology optimizes switching waveforms and reduces electromagnetic interference, while the positive temperature coefficient V_CE(sat) simplifies parallel design, making it suitable for high-current scaling requirements.

Typical Application Areas

Industrial Variable-Frequency Drives: In servo drives and PLC-controlled three-phase motor speed regulation systems, the IKW25N120T2 enhances energy efficiency and dynamic response thanks to its low on-state losses and fast switching characteristics (t_on/t_off on the order of 100 ns).

Uninterruptible Power Supplies (UPS): This device is used in the inverter output stage of online UPS systems to achieve high-efficiency DC-AC conversion. It supports high-frequency PWM modulation (typically ≤20 kHz), and the built-in freewheeling diode optimizes conversion reliability.

Photovoltaic Inverters: In the boost/inverter stages of string or micro-inverters, the 1200V voltage rating meets DC bus voltage requirements, while the high short-circuit withstand time enhances system robustness and complies with IEC 62109 safety standards.

Induction Heating and Welding Power Supplies: Used as the main switching device in resonant topologies such as LLC and ZVS, leveraging its soft-switching characteristics and low tail current to reduce EMI and thermal stress.

Electric Vehicle Charging Infrastructure: Suitable for the power conversion stage of charging stations, meeting the demands of high-voltage, high-current power conversion.
