BCV71

onsemi · Bipolar (BJT) · SOT-23-3

BCV71 from onsemi, in a SOT-23-3. 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 Base input Base terminal of the NPN general-purpose amplifier; the emitter-base voltage is limited to VEBO = 5.0 V (absolute maximum).
2 Emitter passive Emitter terminal of the NPN transistor; the emitter-base limit is VEBO = 5.0 V and DC collector current is rated to 500 mA (absolute maximum).
3 Collector passive Collector terminal of the NPN transistor; absolute maximum ratings are VCEO = 60 V, VCBO = 80 V and DC collector current 500 mA.
