# HL2300

**hongjiacheng** · MOSFETs · SOT-23

HL2300 from hongjiacheng, 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 | G | input | Gate of the N-channel MOSFET; the datasheet gives the gate-source voltage limit as VGS ±10 V. |
| 2 | S | passive | Source of the N-channel MOSFET; the datasheet gives a maximum body-diode continuous current IS of 4.5 A. |
| 3 | D | passive | Drain of the N-channel MOSFET; the datasheet gives VDSS of 20 V and drain current ID of 4.5 A at Ta=25℃. |

## CAD (KiCad official)

- Symbol: `HL2300`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `hl2300-etched.step` / `hl2300-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `hl2300.step` / `hl2300.glb` are the bare package body.
