The BUT34 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
0.7 µs Inductive Fall Time at 25C0095C (Typ)
1.8 µs Inductive Storage Time at 25C0095C (Typ)
• Operating Temperature Range –65 to 200C0095C
