# BCV26

**Nexperia** · Darlington Transistors · SOT-23

BCV26 from Nexperia, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | B | input | Base terminal with DC current gain hFE ≥ 20000 at VCE = -5 V, IC = -100 mA; VBEsat maximum -1.5 V at IC = -100 mA, IB = -0.1 mA. |
| 2 | E | passive | Emitter terminal with maximum emitter-base voltage VEBO = -10 V under open collector condition. |
| 3 | C | passive | Collector terminal with maximum continuous current IC = -500 mA and collector-base breakdown voltage VCBO = -40 V with open emitter. |

## CAD (KiCad official)

- Symbol: `BCV26`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `bcv26-etched.step` / `bcv26-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bcv26.step` / `bcv26.glb` are the bare package body.
