# MMQA6V8T1G

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

MMQA6V8T1G 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 | Protected TVS line 1 (4-line TVS array), 5V reverse working voltage max, ±30kV IEC 61000-4-2 air and contact ESD, I/O-to-GND capacitance 60pF typ, 90pF max. |
| 2 | GND | power_in | Common return node of the TVS array shown in the pin diagram, tied internally to pin 5 (the datasheet refers to GND in the Ppk rating of 150W 8/20µs). |
| 3 | I/O2 | passive | Protected TVS line 2 (4-line TVS array), 5V reverse working voltage max, breakdown 6V min to 9V max at 1mA, clamping 11V max at 4.5A. |
| 4 | I/O3 | passive | Protected TVS line 3 (4-line TVS array), 5V reverse working voltage max, leakage 100nA max at VRWM=5V, clamping 14V max at 10A (8/20µs). |
| 5 | GND | power_in | Common return node of the TVS array shown in the pin diagram, tied internally to pin 2. |
| 6 | I/O4 | passive | Protected TVS line 4 (4-line TVS array), 5V reverse working voltage max, I/O-to-I/O capacitance 30pF typ. |
