Additional Details:

The SSH45N20A is typically available in a TO-220 package. It features a drain-source voltage (Vds) rating of 200V and a continuous drain current (Id) rating that varies depending on the case temperature. The specific Rds(on) value depends on the gate-source voltage (Vgs), and datasheets provide detailed characteristics. This MOSFET is designed to operate over a wide temperature range and is suitable for demanding environments. The fast switching speed allows for operation at higher frequencies, reducing the size of passive components.
