MMBZ5V6ALT3G

onsemi · ESD And Surge Protection (TVS/ESD) · SOT-23

MMBZ5V6ALT3G from onsemi, 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 CATHODE 1 passive Cathode of the first Zener junction; per the datasheet it is used with pin 3 for a unidirectional configuration, and the series has a standard Zener breakdown voltage range of 5.6 V to 47 V.
2 CATHODE 2 passive Cathode of the second Zener junction; per the datasheet it is used with pin 3 for a unidirectional configuration, and pins 1 and 2 together with pin 3 allow a single bidirectional configuration.
3 ANODE passive Common anode shared by both Zener junctions, so the dual common anode design protects two separate lines using only one package.
