BCX56-16TF from Nexperia, in a SOT-89-3. 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 | E | passive | Emitter terminal of the NPN transistor; the datasheet gives an emitter-base breakdown voltage of 5 V minimum and a VEBO rating of 5 V maximum (open collector). |
| 2 | C | passive | Collector terminal of the NPN transistor; the limits are IC of 1 A maximum and ICM of 2 A peak for single pulses with tp ≤ 1 ms, with VCEO of 80 V maximum (open base). |
| 3 | B | passive | Base terminal of the NPN transistor; the limits are IB of 200 mA maximum and IBM of 300 mA peak for single pulses with tp ≤ 1 ms. |
