MMBZ6V8A

JSMSEMI · TVS · SOT-23

MMBZ6V8A from JSMSEMI, 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 K1 passive Cathode of the first Zener TVS diode (unidirectional circuit tied to pins 1 and 3), with VBR 6.46 V min, 6.8 V nom, 7.14 V max at 1.0 mA and VRWM 4.5 V.
2 K2 passive Cathode of the second Zener TVS diode (unidirectional circuit tied to pins 2 and 3), with VBR 6.46 V min, 6.8 V nom, 7.14 V max at 1.0 mA and VRWM 4.5 V.
3 A passive Common anode of both Zener TVS diodes, shared by the pin 1 and pin 2 circuits; the two diodes can be used as two unidirectional channels or one bidirectional configuration.
