Changjing · Bipolar (BJT) · SOT-89-3L
BCX56-16 from Changjing, in a SOT-89-3L. 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 BCX56-16 NPN transistor; base current is rated at 0.1 A DC and 0.2 A peak (tp<1ms). |
| 2 | COLLECTOR | passive | Collector terminal; for the BCX56 variant the collector-base voltage is 100 V and collector-emitter voltage is 80 V maximum, with collector current limited to 1 A and collector power dissipation to 500 mW. |
| 3 | EMITTER | passive | Emitter terminal; emitter-base voltage is rated at 5 V maximum. |
