# PUSB2X4Y

**TECH PUBLIC** · ESD And Surge Protection (TVS/ESD) · SOT-363

PUSB2X4Y from TECH PUBLIC, 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 | IO | passive | ESD-protected I/O line (uni-directional TVS diode to GND), 0.6pF typical I/O to GND, 5.5V max reverse working voltage. |
| 2 | GND | power_in | Ground reference common to all TVS diode channels; I/O pins are protected against GND (±15kV contact, ±20kV air per IEC61000-4-2). |
| 3 | IO | passive | ESD-protected I/O line (uni-directional TVS diode to GND), 0.6pF typical I/O to GND, 5.5V max reverse working voltage. |
| 4 | IO | passive | ESD-protected I/O line (uni-directional TVS diode to GND), 0.6pF typical I/O to GND, 5.5V max reverse working voltage. |
| 5 | NC | unconnected | No connection. |
| 6 | IO | passive | ESD-protected I/O line (uni-directional TVS diode to GND), 0.6pF typical I/O to GND, 5.5V max reverse working voltage. |

## CAD (KiCad official)

- Symbol: `PUSB2X4Y`
- Footprint: `Package_TO_SOT_SMD:SOT-363_SC-70-6`
- 3D model: SOT-363 (KiCad packages3D, STEP)
- 3D model files: `pusb2x4y-etched.step` / `pusb2x4y-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `pusb2x4y.step` / `pusb2x4y.glb` are the bare package body.
