**TECH PUBLIC** · ESD And Surge Protection (TVS/ESD) · SOT-23-6

SRV05-4MR6T1G from TECH PUBLIC, in a SOT-23-6. 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 | ESD/TVS-protected data line (I/O) steering-diode channel, 0.3pF typ I/O to I/O, 0.8pF max to ground, reverse working voltage 5V max. |
| 2 | GND | power_in | Ground reference pin connected to the TVS diode anode, to which all I/O pins are clamped (VRWM 5V max, IEC 61000-4-2 ±25kV air / ±20kV contact). |
| 3 | I/O2 | passive | ESD/TVS-protected data line (I/O) steering-diode channel, 0.3pF typ I/O to I/O, 0.8pF max to ground, reverse working voltage 5V max. |
| 4 | I/O3 | passive | ESD/TVS-protected data line (I/O) steering-diode channel, 0.3pF typ I/O to I/O, 0.8pF max to ground, reverse working voltage 5V max. |
| 5 | VCC | power_in | Power line protection pin connected to the TVS diode cathode (Vcc-GND, 300W peak pulse power at 8/20µs, clamping 18V max at 17A). |
| 6 | I/O4 | passive | ESD/TVS-protected data line (I/O) steering-diode channel, 0.3pF typ I/O to I/O, 0.8pF max to ground, reverse working voltage 5V max. |
