CXT5551-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 NPN transistor; emitter-base breakdown voltage is 6 V minimum and the emitter-base voltage rating is 6 V. |
| 2 | COLLECTOR | passive | Collector of the NPN transistor; VCBO is 180 V, VCEO is 160 V and continuous collector current is 0.6 A. |
| 3 | EMITTER | passive | Emitter of the NPN transistor; the datasheet gives a total power dissipation of 0.5 W and a junction temperature of 150 °C. |
