# BD13610STU

**onsemi** · Bipolar (BJT) · TO-126-3

BD13610STU from onsemi, in a TO-126-3. 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 | Emitter | passive | Emitter terminal of the PNP transistor; the emitter-base voltage is limited to −5 V (VEBO) per the absolute maximum ratings. |
| 2 | Collector | passive | Collector terminal of the PNP transistor; collector-emitter voltage is rated −45 V, −60 V or −80 V (VCEO) for BD136, BD138 and BD140 respectively, with DC collector current limited to −1.5 A. |
| 3 | Base | passive | Base terminal of the PNP transistor; base current is limited to −0.5 A (IB) per the absolute maximum ratings. |
