The D1843 is a Darlington connection transistor with on-chip dumper diode in collector to emitter and zener diode in collector to base. This transistor is ideal for use in acuator drives such as motors, relays, and solenoids.


• High DC current gain due to Darlington connection

• High surge resistance due to on-chip protection elements: C to E: Dumper diode C to B: Zener diode

• Low collector saturation voltage
