# MMBZ6V8ALT1G-ES

**ElecSuper** · Electrostatic And Surge Protection (TVS/ESD) · SOT-23

MMBZ6V8ALT1G-ES from ElecSuper, in a SOT-23. 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 | IO | bidirectional | Connects to an IO data or transmission line to be protected; all pins are rated for ±30 kV IEC 61000-4-2 ESD (air and contact) and the device has a 5.0 V reverse stand-off voltage (VRWM). |
| 2 | IO | bidirectional | Connects to an IO data or transmission line to be protected; all pins are rated for ±30 kV IEC 61000-4-2 ESD (air and contact) and the device has a 5.0 V reverse stand-off voltage (VRWM). |
| 3 | GND | power_in | Connects to ground; the datasheet gives no separate electrical limit for this pin. |
