# PESD18VF1BLYL-TP

**TECH PUBLIC** · ESD And Surge Protection (TVS/ESD) · DFN1006-2

PESD18VF1BLYL-TP from TECH PUBLIC, 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 ESD diode terminal 1 (pin-1 chamfered pad), working voltage 18V max, breakdown 19.5V min at 1mA, and it can be connected to either the signal line or ground since the device is symmetric. |
| 2 | 2 | passive | Bi-directional ESD diode terminal 2, working voltage 18V max, breakdown 19.5V min at 1mA, and it can be connected to either the signal line or ground since the device is symmetric. |
