HXY MOSFET · Bipolar (BJT) · SOT-23
KTC8550S-D-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 | passive | Base of the PNP transistor; the emitter-base voltage must not exceed -5 V (VEBO). |
| 2 | E | passive | Emitter of the PNP transistor; the emitter-base voltage is limited to -5 V (VEBO). |
| 3 | C | passive | Collector of the PNP transistor, rated -80 V collector-base (VCBO), -60 V collector-emitter (VCEO), -1 A continuous and -2 A peak current. |
