SWITCHMODE Series NPN Silicon Power Darlington Transistors with Base-Emitter Speedup Diode

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)
   2.0 µs Inductive Storage Time at 25°C (Typ)
• Operating Temperature Range –65 to 200°C
