Nexperia · Bipolar (BJT) · SOT-89
PBSS5540X from Nexperia, 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 | E | passive | Emitter of the PNP transistor; the device-level limit is VEBO -6 V (open collector). |
| 2 | C | passive | Collector of the PNP transistor; VCEO is -40 V (open base), IC is -4 A continuous, and ICM is -10 A single pulse (tp ≤ 10 ms). |
| 3 | B | passive | Base of the PNP transistor; IB is limited to -1 A continuous and IBM to -2 A single pulse (tp ≤ 1 ms). |
