**Leiditech** · ESD Protection Devices · DFN1006-2

PESD36VS1UL from Leiditech, in a DFN1006-2. 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 | 1 | passive | Bi-directional TVS terminal with 36V reverse working voltage, 40V breakdown at 1mA, and 65V maximum clamping at 4.5A (8/20µs); connect to the protected line, and the polarity is interchangeable with pin 2. |
| 2 | 2 | passive | Bi-directional TVS terminal with 36V reverse working voltage, 40V breakdown at 1mA, and 65V maximum clamping at 4.5A (8/20µs); connect to the protected line or ground, and the polarity is interchangeable with pin 1. |
