AC847BWQ-7

Diodes Incorporated · Bipolar (BJT) · SOT-323

AC847BWQ-7 from Diodes Incorporated, in a SOT-323. 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; the datasheet's top-view pin-out shows it at the bottom-left lead, and the Absolute Maximum Ratings give VEBO 6 V and peak base current IBM 200 mA.
2 E passive Emitter; the datasheet's top-view pin-out shows it at the bottom-right lead, and the Absolute Maximum Ratings give VEBO 6 V.
3 C passive Collector; the datasheet's top-view pin-out shows it as the single lead on the top side, and the Absolute Maximum Ratings give VCBO 50 V, VCEO 45 V, continuous IC 100 mA and peak ICM 200 mA.
