Nexperia · Bipolar (BJT) · SOT-89
PBSS305NX 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 terminal of the NPN transistor; the datasheet limits emitter-base voltage VEBO to 5 V (open collector). |
| 2 | C | passive | Collector terminal; limits are VCEO 80 V (open base), IC 4.6 A continuous and ICM 9.2 A peak for single pulses with tp ≤ 1 ms. |
| 3 | B | passive | Base terminal used to drive the transistor; the datasheet gives no base voltage limit, only base-current test conditions such as IB = 200 mA for IC = 4 A saturation. |
