Infineon IKP20N60H3 600V 20A N-Channel Power MOSFET for High-Efficiency Switching Applications

The demand for high-efficiency power conversion continues to grow across industries such as industrial motor drives, renewable energy systems, and switched-mode power supplies (SMPS). To meet these demands, power MOSFETs must offer low losses, high reliability, and robust performance. The Infineon IKP20N60H3 is a 600V, 20A N-channel power MOSFET engineered specifically for these challenging high-efficiency switching applications.

Built upon Infineon’s advanced CoolMOS™ H3 superjunction technology, this MOSFET sets a new benchmark for efficiency and power density. The technology significantly reduces the device’s key figure of merit, on-state resistance (RDS(on)), which is as low as 0.19Ω. This minimal resistance directly translates to lower conduction losses, allowing the transistor to handle high currents with improved thermal performance and reduced need for heat sinking.

A critical advantage for switching applications is the device’s exceptional switching performance. The IKP20N60H3 features very low gate charge (Qg) and low effective output capacitance (Coss(eff)), enabling faster switching speeds. This reduces switching losses, which is paramount for operating at higher frequencies. The ability to switch efficiently at higher frequencies allows designers to shrink the size of magnetic components like transformers and inductors, leading to more compact and lighter end-products.

Beyond performance, the device is designed for ruggedness and reliability. It offers excellent avalanche ruggedness and is characterized by high dv/dt capability, enhancing its durability in harsh operating environments and protecting against voltage spikes. The integrated fast body diode ensures improved reverse recovery characteristics, which is crucial for circuits like power factor correction (PFC) and half-bridge topologies.

The TO-220 package provides a robust industry-standard form factor, ensuring mechanical stability and efficient heat dissipation from the tab. This makes the IKP20N60H3 an ideal choice for a wide array of applications, including:

High-power AC-DC and DC-DC converters

Motor control and drive systems

Solar inverters and UPS systems

Industrial lighting and welding equipment
