# PUSB2X4Y-N

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

PUSB2X4Y-N from BORN, 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 | I/O | bidirectional | Protected data/power line of the ESD diode array, rated for a 5.0 V reverse stand-off voltage (VRWM) and 6 V minimum reverse breakdown voltage (VBR at 1 mA). |
| 2 | GND | power_in | Ground reference for the ESD protection diode array; the I/O-to-GND junction capacitance is 0.35 pF typical and 0.5 pF maximum at VR = 0 V, 1 MHz. |
| 3 | I/O | bidirectional | Protected data/power line of the ESD diode array, rated for IEC 61000-4-2 ±15 kV contact and ±20 kV air discharge. |
| 4 | I/O | bidirectional | Protected data/power line of the ESD diode array, rated for IEC 61000-4-4 (EFT) 40 A (5/50 ns) and IEC 61000-4-5 (lightning) 3.5 A (8/20 µs). |
| 5 | Vcc | power_in | Supply-side pin of the ESD diode array as labeled on the schematic; the datasheet gives no separate supply voltage rating for this pin. |
| 6 | I/O | bidirectional | Protected data/power line of the ESD diode array, with 0.25 pF typical I/O-to-I/O junction capacitance and 60 W peak pulse power (tp = 8/20 µs). |
