# KY2300

**KY** · MOSFETs · SOT-23

KY2300 from KY, 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 terminal; the gate-source voltage is rated at ±12 V (VGS). |
| 2 | SOURCE | passive | Source terminal, the reference for the drain-source rating of 20 V (VDS) and the gate-source rating of ±12 V (VGS). |
| 3 | DRAIN | passive | Drain terminal; drain-source voltage is rated at 20 V (VDS) with 5 A continuous drain current (ID). |

## CAD (KiCad official)

- Symbol: `KY2300`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `ky2300-etched.step` / `ky2300-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ky2300.step` / `ky2300.glb` are the bare package body.
