# PESD5V0L5UY-TP

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

PESD5V0L5UY-TP 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 | I/O1 | passive | Protected I/O line (Note 1 lists pin 1 as an I/O pin); unidirectional TVS channel with 5 V working voltage, rated for ±30 kV IEC 61000-4-2 contact and air discharge. |
| 2 | GND | power_in | Common ground/reference node of the 5-line TVS array, shown in the pin configuration tied to the common diode bus; not listed as an I/O pin in Note 1. |
| 3 | I/O2 | passive | Protected I/O line (Note 1 lists pin 3 as an I/O pin); unidirectional TVS channel with 5 V max reverse working voltage and 6 V min breakdown at 1 mA. |
| 4 | I/O3 | passive | Protected I/O line (Note 1 lists pin 4 as an I/O pin); clamping voltage 10 V max at IPP=1 A (8x20 µs). |
| 5 | I/O4 | passive | Protected I/O line (Note 1 lists pin 5 as an I/O pin); junction capacitance 80 pF typical at VR=0 V, f=1 MHz. |
| 6 | I/O5 | passive | Protected I/O line (Note 1 lists pin 6 as an I/O pin); peak pulse current 10 A (8/20 µs) per the ratings. |
