# LBAV74LT1G

**LRC** · Switching Diodes · SOT-23

LBAV74LT1G from LRC, 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 one of the two switching diodes; each diode is rated for 50 Vdc reverse voltage and 200 mAdc forward current. |
| 2 | ANODE | passive | Anode of the second switching diode per the pinout diagram; the package drawing note on page 3 instead lists pin 2 as 'NO CONECTION', so confirm before use. |
| 3 | CATHODE | passive | Cathode shared by the two diodes, with pins 1 and 2 as the anodes; maximum reverse voltage is 50 Vdc and forward current is 200 mAdc per diode. |

## CAD (KiCad official)

- Symbol: `LBAV74LT1G`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `lbav74lt1g-etched.step` / `lbav74lt1g-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lbav74lt1g.step` / `lbav74lt1g.glb` are the bare package body.
