20N60S5 OLD TESTED 600V 20A IGBT PACK OF 2PCS

The 20N60S5 (often branded by Infineon/CoolMOS) is a high-performance Power MOSFET/IGBT (Insulated Gate Bipolar Transistor) designed for high-voltage and high-speed switching. While the “S5” series is technically a Superjunction MOSFET, it is often used in the same high-power roles as an IGBT.

​Short Description & Key Specs

​Voltage Rating (V_{DS}): 600V (Suitable for direct mains AC applications).

​Current Rating (I_D): 20A (Continuous current handling at 25°C).

​Technology: CoolMOS™ S5. It is designed for “hard-switching” topologies, meaning it can turn on and off very fast with minimal energy loss.

​Package: TO-220 or TO-247 (Standard 3-pin power package).

​Primary Uses

​Solar Inverters: Used in the power conversion stage to turn DC battery/panel power into 220V/110V AC.

​UPS (Uninterruptible Power Supplies): Switches power sources instantly when a blackout occurs.

​Welding Inverters: Manages the high-frequency switching required to create a stable welding arc.

​PFC Circuits (Power Factor Correction): Used in large power supplies (like server or gaming PC units) to improve electrical efficiency.

• ​Motor Drives: Controlling the speed of industrial AC motors or high-voltage DC motors
