# BCX17T116

**ROHM Semicon** · Bipolar (BJT) · TO-236-3(SOT-23-3)

BCX17T116 from ROHM Semicon, in a TO-236-3(SOT-23-3). 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 | E | passive | Emitter of the PNP transistor; the datasheet lists pin (1) as Emitter, with VEBO rated at -5 V. |
| 2 | B | passive | Base of the PNP transistor; the datasheet lists pin (2) as Base, with IC rated at -500 mA and ICP at -1 A. |
| 3 | C | passive | Collector of the PNP transistor; the datasheet lists pin (3) as Collector, with VCES rated at -50 V and VCEO at -45 V. |

## CAD (KiCad official)

- Symbol: `BCX17T116`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: TO-236-3(SOT-23-3) (KiCad packages3D, STEP)
- 3D model files: `bcx17t116-etched.step` / `bcx17t116-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bcx17t116.step` / `bcx17t116.glb` are the bare package body.
