MMBTSC3875L

PJSEMI · Bipolar (BJT) · SOT-23

MMBTSC3875L 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; emitter-base voltage rating VEBO is 5 V and emitter-base cutoff current IEBO is at most 100 nA at VEB = 5 V.
2 Emitter passive Emitter terminal of the NPN transistor; the device is rated for a collector current IC of 150 mA maximum.
3 Collector passive Collector terminal of the NPN transistor; rated for VCBO of 60 V and VCEO of 50 V, with collector current IC up to 150 mA.
