2SA1837-OSEN

OSEN · Bipolar Transistors - BJT · TO-220F

2SA1837-OSEN from OSEN, in a TO-220F. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 B input Base; the datasheet rates continuous base current at 0.1 A and emitter-base voltage at 5 V.
2 C passive Collector; the datasheet rates collector-base and collector-emitter voltage at 230 V and continuous collector current at 1 A.
3 E passive Emitter; the datasheet rates emitter-base voltage at 5 V.
