# ESDA6V8AV6

**TECH PUBLIC** · ESD And Surge Protection (TVS/ESD) · SOT-563

ESDA6V8AV6 from TECH PUBLIC, in a SOT-563. 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 | IO1 | passive | Protected line connection on the bottom row of the SOT563 pin-configuration drawing; ESD rated ±20kV air / ±18kV contact per IEC 61000-4-2, 10pF max junction capacitance IO to Gnd. |
| 2 | GND | power_in | Common ground/return node of the 5-line TVS array, which the drawing shows as the center bottom pin tied to the internal bus; the capacitance spec is stated for IO to Gnd. |
| 3 | IO2 | passive | Protected line connection on the bottom row of the SOT563 pin-configuration drawing; reverse working voltage 5V max, breakdown voltage 6V min at 1mA. |
| 4 | IO3 | passive | Protected line connection on the top row of the SOT563 pin-configuration drawing; reverse working voltage 5V max, clamping voltage 14V max at IPP=4A (8x20us). |
| 5 | IO4 | passive | Protected line connection on the top row, center position, of the SOT563 pin-configuration drawing; reverse leakage 0.1uA max at VRWM=5V. |
| 6 | IO5 | passive | Protected line connection on the top row of the SOT563 pin-configuration drawing; ESD rated ±20kV air / ±18kV contact per IEC 61000-4-2. |
