PXT8550-JSM
JSMSEMI · Bipolar (BJT) · SOT-89
PXT8550-JSM from JSMSEMI, 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 | BASE | input | Base of the PNP transistor; VEBO max rating is -5 V and base-emitter on voltage is max -1 V at IC=-1 V, VCE=-10 mA. |
| 2 | COLLECTOR | passive | Collector of the PNP transistor; VCBO -40 V, VCEO -25 V, continuous IC -1.5 A, power dissipation 0.5 W. |
| 3 | EMITTER | passive | Emitter of the PNP transistor; emitter-base breakdown voltage V(BR)EBO min -5 V at IE=-100 µA. |
