# BAS70-05

**BORN** · Schottky Diodes · SOT-23

BAS70-05 from BORN, in a SOT-23. 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 | A1 | passive | Anode of the first Schottky diode (70 V max reverse voltage, 70 mA forward continuous current), per the BAS70-05 circuit drawing. |
| 2 | A2 | passive | Anode of the second Schottky diode (70 V max reverse voltage, 70 mA forward continuous current), per the BAS70-05 circuit drawing. |
| 3 | K | passive | Common cathode of both Schottky diodes in the BAS70-05 (marking code 75), shown as the top pin in the package drawing. |

## CAD (KiCad official)

- Symbol: `BAS70-05`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `bas70-05-etched.step` / `bas70-05-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bas70-05.step` / `bas70-05.glb` are the bare package body.
