SWITCHMODE Series

NPN Silicon Power Darlington Transistors with Base-Emitter Speedup Diode

The BUT34 Darlingtontransistor is designed for high–voltage, high–speed, power switchingin 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
