# SMF05C.TCT-HXY

**HXY MOSFET** · ESD And Surge Protection (TVS/ESD) · SOT-363

SMF05C.TCT-HXY from HXY MOSFET, in a SOT-363. 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 | IO1 | passive | ESD-protected line steered by a diode pair to the positive and negative rails, with 5V reverse working voltage and 100 pF max junction capacitance at 0V. |
| 2 | GND | power_in | Negative rail of the array, connected to system ground in typical applications. |
| 3 | IO2 | passive | ESD-protected line steered by a diode pair to the positive and negative rails, with 5V reverse working voltage and 100 pF max junction capacitance at 0V. |
| 4 | IO3 | passive | ESD-protected line steered by a diode pair to the positive and negative rails, with 5V reverse working voltage and 100 pF max junction capacitance at 0V. |
| 5 | IO4 | passive | ESD-protected line steered by a diode pair to the positive and negative rails, with 5V reverse working voltage and 100 pF max junction capacitance at 0V. |
| 6 | IO5 | passive | ESD-protected line steered by a diode pair to the positive and negative rails, with 5V reverse working voltage and 100 pF max junction capacitance at 0V. |

## CAD (KiCad official)

- Symbol: `SMF05C.TCT-HXY`
- Footprint: `Package_TO_SOT_SMD:SOT-363_SC-70-6`
- 3D model: SOT-363 (KiCad packages3D, STEP)
- 3D model files: `smf05c-tct-hxy-etched.step` / `smf05c-tct-hxy-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `smf05c-tct-hxy.step` / `smf05c-tct-hxy.glb` are the bare package body.
