2DA1971-7

Diodes Incorporated · Bipolar (BJT) · SOT-89

2DA1971-7 from Diodes Incorporated, in a SOT-89. 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 of the PNP transistor; base current IB is limited to -250 mA and VEBO to -7 V.
2 C passive Collector, also connected to the exposed collector tab; VCEO -400 V, IC -0.5 A continuous, ICM -1 A peak.
3 E passive Emitter of the PNP transistor; emitter-base breakdown voltage BVEBO is -7 V at IE = -100 µA.
