Additional Details

The UF9640L typically features a drain-source voltage (VDS) rating of 600V and a continuous drain current (ID) rating of around 4.5A. The on-resistance (RDS(on)) is typically low, which contributes to reduced power losses. It is commonly available in through-hole packages such as TO-220 or TO-220F. Specific values for gate charge, input capacitance, and output capacitance are usually provided in the manufacturer's datasheet. It's designed to operate efficiently in both hard-switching and soft-switching applications, and its low gate charge makes it easy to drive.
