MMBZ5V6ALT1G

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

MMBZ5V6ALT1G 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 of the dual common-anode device; used with pin 3 as one unidirectional Zener line (circuit tied to pins 1 and 3), with 24 W peak power at 1.0 ms for the MMBZ5V6ALT1G.
2 CATHODE 2 passive Cathode of the second Zener junction of the dual common-anode device; used with pin 3 as a second unidirectional Zener line (circuit tied to pins 2 and 3), with 24 W peak power at 1.0 ms for the MMBZ5V6ALT1G.
3 ANODE passive Common anode shared by both Zener junctions, which the datasheet states allows two separate unidirectional configurations or a single bidirectional configuration; the MMBZ5V6ALT1G has a 5.6 V nominal breakdown voltage.
