# MMQA5V6T1G

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

MMQA5V6T1G 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 | IO1 | passive | ESD-protected line input/output (top-left of the diagram), protected to ±30 kV air/contact per IEC 61000-4-2 and sharing the top diode branch with pin 6. |
| 2 | GND | power_in | Ground reference, tied internally to pin 5 via the central rail in the pin configuration diagram; the datasheet tests junction capacitance as IO to GND. |
| 3 | IO2 | passive | ESD-protected line input/output (bottom-left of the diagram), protected to ±30 kV air/contact per IEC 61000-4-2 and sharing the bottom diode branch with pin 4. |
| 4 | IO3 | passive | ESD-protected line input/output (bottom-right of the diagram), protected to ±30 kV air/contact per IEC 61000-4-2 and sharing the bottom diode branch with pin 3. |
| 5 | GND | power_in | Ground reference, tied internally to pin 2 via the central rail in the pin configuration diagram. |
| 6 | IO4 | passive | ESD-protected line input/output (top-right of the diagram), protected to ±30 kV air/contact per IEC 61000-4-2 and sharing the top diode branch with pin 1. |
