Nexperia · Bipolar (BJT) · SOT-143-4
BCV62B from Nexperia, in a SOT-143-4. 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 | C2 / B1+B2 (collector TR2; base TR1 and TR2) | passive | Pin 1 is shared: it is the collector of TR2 and the common base connection of both TR1 and TR2, as stated in the pinning table. |
| 2 | C1 (collector TR1) | passive | Collector of PNP transistor TR1; per-transistor limits are VCBO and VCEO of −30 V, IC of −100 mA and peak ICM of −200 mA. |
| 3 | E1 (emitter TR1) | passive | Emitter of PNP transistor TR1; the datasheet gives an emitter-base voltage limit VEBS of −6 V (max, with VCE = 0 V). |
| 4 | E2 (emitter TR2) | passive | Emitter of PNP transistor TR2; the datasheet gives an emitter current limit IE2 of −5 mA (max, with VCE1 = −5 V) for the matched current-mirror test. |
