# ESDA6V1-5P6

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

ESDA6V1-5P6 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 | ESD-protected I/O line 1, clamped by a diode to the common bus (pin 2); 5V reverse working voltage, ±30kV IEC 61000-4-2. |
| 2 | GND | power_in | Common ground bus to which all five protection diodes connect; reference for the 5V working voltage and for IO-to-Gnd capacitance. |
| 3 | IO2 | passive | ESD-protected I/O line 2, clamped by a diode to the common bus (pin 2); 5V reverse working voltage, ±30kV IEC 61000-4-2. |
| 4 | IO3 | passive | ESD-protected I/O line 3, clamped by a diode to the common bus (pin 2); 5V reverse working voltage, ±30kV IEC 61000-4-2. |
| 5 | IO4 | passive | ESD-protected I/O line 4, clamped by a diode to the common bus (pin 2); 5V reverse working voltage, ±30kV IEC 61000-4-2. |
| 6 | IO5 | passive | ESD-protected I/O line 5, clamped by a diode to the common bus (pin 2); 5V reverse working voltage, ±30kV IEC 61000-4-2. |
