MMBT2907ALT1HTSA1

Infineon Technologies · Bipolar (BJT) · SOT-23

MMBT2907ALT1HTSA1 from Infineon Technologies, 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 terminal; the datasheet's maximum ratings give a base current IB of 100 and a peak base current IBM of 200 (unit not printed in the text, presumably mA).
2 E passive Emitter terminal; the emitter-base voltage VEBO is rated at a maximum of 5 V.
3 C passive Collector terminal; the collector-emitter voltage VCEO is rated at 60 V and the collector current IC at 600 mA.
