2DA1797Q-13

Diodes Incorporated · Bipolar (BJT) · SOT-89

2DA1797Q-13 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 input Base of the PNP transistor; the pin-out drawing shows it as the pin opposite the emitter, on the same side as the collector pin.
2 C passive Collector, rated VCEO -50 V, continuous IC -3 A and peak ICM -6 A; it is also connected to the exposed collector tab.
3 E passive Emitter of the PNP transistor, with a maximum emitter-base voltage VEBO of -6 V.
