Diodes Incorporated · Bipolar (BJT) · SOT-89
BCX5110TA 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 of the PNP transistor; the datasheet gives IB = -100 mA continuous and IBM = -200 mA peak pulse, with VEBO of -5 V. |
| 2 | C | passive | Collector of the PNP transistor, also the exposed collector tab used as the heat-sinking pad; the datasheet gives IC = -1 A continuous, ICM = -2 A peak, and VCEO of -45 V for the BCX51 family. |
| 3 | E | passive | Emitter of the PNP transistor; the datasheet gives a maximum emitter-base voltage VEBO of -5 V. |
