PJSEMI · Bipolar (BJT) · SOT-23
MMBTSC1623-L5 from PJSEMI, 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 | Base | input | Base terminal of the NPN transistor; the emitter-base voltage rating VEBO is 5 V and the emitter-base cutoff current IEBO is 0.1 µA maximum at VEB = 5 V. |
| 2 | Emitter | passive | Emitter terminal of the NPN transistor; the maximum collector current rating is 100 mA and the emitter-base breakdown voltage V(BR)EBO is 5 V minimum at IE = 100 µA. |
| 3 | Collector | passive | Collector terminal of the NPN transistor; ratings are VCBO 60 V, VCEO 50 V, IC 100 mA and PD 200 mW at 25 ℃ ambient. |
