# SZNUD3124LT1G

**onsemi** · Brushed DC Motor Drivers · SOT-23

SZNUD3124LT1G 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 | GATE | input | Gate input accepts logic-level drive, and the datasheet rates the continuous gate-to-source voltage at 12 V (TJ = 125°C). |
| 2 | SOURCE | passive | Source terminal of the internal MOSFET; the datasheet gives no separate pin-level rating beyond the device maximum ratings. |
| 3 | DRAIN | passive | Drain connects to the inductive load, with a continuous drain-to-source voltage rating of 28 V and a continuous drain current rating of 150 mA (TJ = 125°C). |

## CAD (KiCad official)

- Symbol: `SZNUD3124LT1G`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `sznud3124lt1g-etched.step` / `sznud3124lt1g-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sznud3124lt1g.step` / `sznud3124lt1g.glb` are the bare package body.
