JSMSEMI · Bipolar (BJT) · SOT-89
2SD2391-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 voltage is rated at 6 V maximum (VEBO) and IEBO is 0.1 µA max at VEB=5 V. |
| 2 | COLLECTOR | passive | Collector, rated 60 V (VCBO and VCEO) and 2 A continuous (IC), with 0.5 W collector power dissipation; also the SOT-89 tab per the package drawing. |
| 3 | EMITTER | passive | Emitter of the NPN transistor; the datasheet prints the label as 'EMMITTER' on pin 3. |
