BCV71-QR

Nexperia · Bipolar (BJT) · TO-236AB

BCV71-QR from Nexperia, in a TO-236AB. 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 passive Base of the NPN transistor; the datasheet gives a peak base current limit of 200 mA (single pulse, tp ≤ 1 ms) in Table 5.
2 E passive Emitter of the NPN transistor; the datasheet gives an emitter-base voltage limit of 5 V (open collector) in Table 5.
3 C passive Collector of the NPN transistor; the datasheet gives a collector current limit of 100 mA and a collector-emitter voltage limit of 60 V (open base) in Table 5.
