Additional Details

The MTM40N20 typically comes in a TO-220 or similar through-hole package. Key specifications include a drain-source voltage (VDS) of 200V, a gate-source voltage (VGS) of ±20V, and a continuous drain current (ID) that varies depending on the case temperature (consult the datasheet for specific values). The gate threshold voltage (VGS(th)) is typically in the range of 2V to 4V. The device's on-resistance (RDS(on)) is a critical parameter, and it is usually specified at a particular gate-source voltage and drain current. Proper gate drive circuitry is essential for optimal performance. Consult the datasheet for detailed electrical characteristics, thermal performance, and application recommendations. This MOSFET is designed to handle high-speed switching, minimizing switching losses in power conversion applications.
