8050SS

Changjing · Bipolar (BJT) · TO-92

8050SS from Changjing, 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 of the NPN transistor; VEBO max 5 V (V(BR)EBO min 5 V at IE=0.1 mA).
2 COLLECTOR passive Collector of the NPN transistor; VCBO 40 V, VCEO 25 V, IC max 1.5 A.
3 BASE passive Base of the NPN transistor; drives the device with hFE(1) of 85-300 at VCE=1 V, IC=100 mA.
