# BAV70

**Nexperia** · Switching Diodes · SOT-23

BAV70 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 | A1 | passive | Anode of diode 1. Forward voltage typically up to 855 mV at IF = 10 mA. Max forward current 215 mA per diode at Tamb ≤ 25 °C. |
| 2 | A2 | passive | Anode of diode 2. Forward voltage typically up to 855 mV at IF = 10 mA. Max forward current 215 mA per diode at Tamb ≤ 25 °C. |
| 3 | CC | passive | Common cathode for both diodes. Reverse voltage rating VR ≤ 100 V. Total device forward current 125 mA at Tamb ≤ 25 °C. |

## Ordering variants

Same part, different packaging or reel option.

- `BAV70`

## CAD (KiCad official)

- Symbol: `BAV70`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `bav70-etched.step` / `bav70-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bav70.step` / `bav70.glb` are the bare package body.
