2SA1797-Q
Foshan Blue Rocket Elec · Bipolar (BJT) · SOT-89
2SA1797-Q from Foshan Blue Rocket Elec, 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 | Base | input | Base terminal of the PNP transistor; the datasheet gives emitter-base breakdown VEBO of -6.0 V (min -6.0 V at IE=-50μA) and emitter-base cut-off current IEBO of -0.1 μA max at VEB=-5.0 V. |
| 2 | Collector | passive | Collector terminal; the datasheet limits are VCBO -50 V, VCEO -50 V, continuous collector current IC -3.0 A and pulsed ICP -6.0 A, with 0.5 W collector dissipation (2.0 W when mounted on a 40×40×0.7 mm ceramic board). |
| 3 | Emitter | passive | Emitter terminal, the common reference for the base and collector; the datasheet gives emitter-base rating VEBO of -6.0 V. |
