MMBTSC1623

ST Semtech · Bipolar (BJT) · SOT-23

MMBTSC1623 from ST Semtech, 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 B input Base of the NPN transistor; DC current gain hFE is graded O/Y/G/L at VCE = 6 V, IC = 1 mA, and VEBO is limited to 5 V.
2 E passive Emitter of the NPN transistor; emitter-base voltage is limited to 5 V.
3 C passive Collector of the NPN transistor; VCBO is 60 V, VCEO is 50 V and collector current is up to 100 mA.
