Additional Details

The SiHFR420A is typically available in a TO-252 package. Key specifications include a drain-source voltage (VDS) of 250V and a continuous drain current (ID) which varies depending on the case temperature. The device’s low RDS(on) and gate charge contribute to higher efficiency and faster switching speeds. The high avalanche energy rating provides protection against transient voltage spikes. Always refer to the datasheet for specific operating conditions and performance characteristics.
