# HL3416

**hongjiacheng** · MOSFETs · SOT-23

HL3416 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 terminal; the gate-source voltage is rated at ±10 V maximum (VGS). |
| 2 | S | passive | Source terminal; the body diode forward voltage VSD is at most 1.0 V at IS = 1.0 A and VGS = 0 V. |
| 3 | D | passive | Drain terminal; the drain-source voltage is rated at 20 V maximum, with continuous drain current ID of 6.5 A at TA = 25 °C (steady state) and 28 A pulsed. |

## CAD (KiCad official)

- Symbol: `HL3416`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `hl3416-etched.step` / `hl3416-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `hl3416.step` / `hl3416.glb` are the bare package body.
