# HSM36.TCT

**HXY MOSFET** · Electrostatic And Surge Protection (TVS/ESD) · SOT-23

HSM36.TCT from HXY MOSFET, 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 | I/O1 | passive | Protected line 1, connected to the first diode of the circuit diagram; the part has a 36V working voltage and 350W (8/20us) peak pulse power. |
| 2 | I/O2 | passive | Protected line 2, connected to the second diode of the circuit diagram; it can protect a second unidirectional line, with a 36V working voltage and ±30kV ESD rating. |
| 3 | COMMON | passive | Common node joining both diodes in the circuit diagram; with pin 1 or 2 it protects one bidirectional line. |

## CAD (KiCad official)

- Symbol: `HSM36.TCT`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `hsm36-tct-etched.step` / `hsm36-tct-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `hsm36-tct.step` / `hsm36-tct.glb` are the bare package body.
