Slkor SLKORMICRO Elec · Bipolar (BJT) · SOT-89
PBSS304 from Slkor SLKORMICRO Elec, 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 NPN transistor; drives IC up to 5A continuous (IB max 2A, VEBO max 7V). |
| 2 | C | passive | Collector (middle pin, electrically common with the collector tab); VCEO 60V, VCBO 150V, IC 5A continuous and 20A peak. |
| 3 | E | passive | Emitter of the NPN transistor; reference terminal for VCE and VBE. |
