2DB1188Q-13

Diodes Incorporated · Bipolar (BJT) · SOT-89

2DB1188Q-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 third lead in the E, C, B order.
2 C passive Collector of the PNP transistor (VCEO -32V, IC -2A continuous); it is also connected to the exposed collector tab.
3 E passive Emitter of the PNP transistor; the pin-out drawing shows it as the first lead in the E, C, B order.
