BC337-40

LGE · Bipolar (BJT) · TO-92

BC337-40 from LGE, in a TO-92. 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 EMITTER passive Emitter terminal of the BC337-40 NPN transistor, rated with emitter-base breakdown VEBO of 5 V and continuous collector current IC of 800 mA.
2 BASE passive Base terminal of the NPN transistor, with base-emitter saturation voltage VBE(sat) of 1.2 V at IC=500 mA, IB=50 mA.
3 COLLECTOR passive Collector terminal, rated VCEO of 45 V for BC337 (25 V for BC338), IC of 800 mA continuous, and total device dissipation PD of 625 mW.
