Designer's
56 AMPERES NPN SILICON POWER DARLINGTON TRANSISTOR 600 VOLTS 250 WATTS
The BUT33 Darlington transistor is designed for high–voltage, high–speed, power switching in inductive circuits where fall time is critical. They are particularly suited for line operated SWITCHMODE applications such as: AC and DC Motor Controls Switching Regulators Inverters Solenoid and Relay Drivers Fast Turn Off Times 800 ns Inductive Fall Time at 25_C (Typ) 2.
