BCX5210TA from Diodes Incorporated, in a SOT-89. 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 | input | Base; the datasheet's top-view pin-out shows it as the bottom lead, with IB rated -100 mA continuous and -200 mA peak, and VEBO of -5 V. |
| 2 | C | passive | Collector (centre lead, also connected to the exposed collector tab); the datasheet rates IC at -1 A continuous and -2 A peak, with VCEO of -45 V for BCX51, -60 V for BCX52 and -80 V for BCX53. |
| 3 | E | passive | Emitter; the datasheet's top-view pin-out shows it as the top lead, with VEBO of -5 V. |
