HXY MOSFET · Bipolar (BJT) · SOT-23
PBSS4350T-HXY from HXY MOSFET, in a SOT-23. 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; the datasheet rates emitter-base voltage at 5 V maximum (VEBO). |
| 2 | E | passive | Emitter of the NPN transistor; the datasheet rates continuous collector current at 2 A maximum. |
| 3 | C | passive | Collector of the NPN transistor; the datasheet rates collector-emitter voltage at 50 V and collector-base voltage at 50 V maximum. |
