2SA1213SQ-Y from PJSEMI, 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 voltage -VEBO of 5 V max and emitter-base cutoff current of 100 nA max at VEB = -5 V. |
| 2 | Collector | passive | Collector terminal; absolute maximum ratings are collector-base voltage -VCBO 50 V, collector-emitter voltage -VCEO 50 V, and collector current -IC 2 A. |
| 3 | Emitter | passive | Emitter terminal; the datasheet gives emitter-base breakdown voltage V(BR)EBO of 5 V min at IE = -100 μA, and maximum power dissipation PD of 0.5 W for the device. |
