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. |
