# HSZNUP2115LT1G

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

HSZNUP2115LT1G 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 | A1 | passive | Protected line terminal of one bidirectional TVS diode to common pin 3, with VRWM 24 V max and VBR 26 V min to 33 V max at 1 mA. |
| 2 | A2 | passive | Second protected line terminal of the other TVS diode to common pin 3, with VRWM 24 V max and VBR 26 V min to 33 V max at 1 mA. |
| 3 | COMMON | passive | Common junction of both diodes in the circuit diagram, shared with pins 1 and 2 as the reference node of the ESD protection (IEC61000-4-2 ±30 kV air and contact). |

## CAD (KiCad official)

- Symbol: `HSZNUP2115LT1G`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `hsznup2115lt1g-etched.step` / `hsznup2115lt1g-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `hsznup2115lt1g.step` / `hsznup2115lt1g.glb` are the bare package body.
