MMBTA92LT1G-CN

ChipNobo · Bipolar (BJT) · SOT-23

MMBTA92LT1G-CN from ChipNobo, 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 of the PNP transistor; VEBO max is -6 V and emitter-base breakdown V(BR)EBO is -6 V at IE=-100uA.
2 EMITTER passive Emitter of the PNP transistor; collector current is rated up to -500 mA continuous.
3 COLLECTOR passive Collector of the PNP transistor; VCBO and VCEO are rated -300 V, with 300 mW collector power dissipation.
