# BAT54CLT3G

**onsemi** · Schottky Diodes · SOT-23

BAT54CLT3G 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 of the first Schottky diode in the dual common-cathode pair; each diode is rated for 30 V reverse voltage and 200 mA maximum DC forward current. |
| 2 | ANODE | passive | Anode of the second Schottky diode in the dual common-cathode pair; each diode is rated for 30 V reverse voltage and 200 mA maximum DC forward current. |
| 3 | CATHODE | passive | Common cathode shared by both diodes, rated for the 30 V reverse voltage and 200 mA maximum DC forward current given in the maximum ratings. |

## CAD (KiCad official)

- Symbol: `BAT54CLT3G`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `bat54clt3g-etched.step` / `bat54clt3g-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bat54clt3g.step` / `bat54clt3g.glb` are the bare package body.
