# BAS70LT1G

**onsemi** · Schottky Diodes · SOT-23

BAS70LT1G from onsemi, 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 | ANODE | passive | Anode terminal of the Schottky barrier diode, per the SOT-23 Style 8 pin assignment; the device is rated for 70 V reverse voltage and 70 mA forward current (TJ = 150°C). |
| 2 | NC | unconnected | Marked NO CONNECTION in the SOT-23 Style 8 pin assignment, so it has no connection to the diode. |
| 3 | CATHODE | passive | Cathode terminal of the Schottky barrier diode, per the SOT-23 Style 8 pin assignment; the device is rated for 70 V reverse voltage and 70 mA forward current (TJ = 150°C). |

## CAD (KiCad official)

- Symbol: `BAS70LT1G`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `bas70lt1g-etched.step` / `bas70lt1g-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bas70lt1g.step` / `bas70lt1g.glb` are the bare package body.
