# HXY2102EI

**HXY MOSFET** · MOSFETs · SOT-323

HXY2102EI from HXY MOSFET, in a SOT-323. 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 | G | input | Gate terminal of the N-channel MOSFET; the gate-source voltage is rated at ±12 V (VGS) in the absolute maximum ratings. |
| 2 | D | passive | Drain terminal of the N-channel MOSFET; the drain-source voltage is rated at 20 V (VDS) with 2 A continuous drain current (ID). |
| 3 | S | passive | Source terminal of the N-channel MOSFET; the maximum continuous body-diode forward current is 1.0 A (IS). |

## CAD (KiCad official)

- Symbol: `HXY2102EI`
- Footprint: `Package_TO_SOT_SMD:SOT-323_SC-70`
- 3D model: SOT-323 (KiCad packages3D, STEP)
- 3D model files: `hxy2102ei-etched.step` / `hxy2102ei-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `hxy2102ei.step` / `hxy2102ei.glb` are the bare package body.
