TRANSISTOR
2SD1843
NPN SILICON EPITAXIAL
TRANSISTOR (DARLINGTON CONNECTION) FOR LOW-FREQUENCY POWER AMPLIFIERS AND LOW-SPEED SWITCHING
The 2SD1843 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.
PACKAGE DRAWING (UNIT: mm)
FEATURES
• 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
