2SA1797G-B-AB3-R

UTC Unisonic Tech · Bipolar (BJT) · SOT-89-3

2SA1797G-B-AB3-R from UTC Unisonic Tech, in a SOT-89-3. 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 passive Base terminal of the PNP transistor; the datasheet specifies VCE(SAT) of -0.35V max at IC/IB = -1A/-50mA, with the base driven at -50mA for that rating.
2 C passive Collector terminal; limited to -2A DC (-5A pulse, PW=10ms), VCBO and VCEO of -50V, and 0.5W collector power dissipation for the SOT-89 package.
3 E passive Emitter terminal; the emitter-base breakdown voltage is -6V (VEBO) and the device is rated to a junction temperature of 150°C.
