MMBZ27VALFHT116

ROHM Semicon · TVS · SOT-23

MMBZ27VALFHT116 from ROHM Semicon, 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 passive Cathode of the first TVS diode (unidirectional, dual-diode common-anode device) with VRWM 22.0 V and VBR 25.65 to 28.35 V at 1 mA.
2 Cathode passive Cathode of the second TVS diode (unidirectional, dual-diode common-anode device) with VRWM 22.0 V and VBR 25.65 to 28.35 V at 1 mA.
3 Anode passive Common anode of both TVS diodes, typically tied to ground, with 40 W peak pulse power (10/1000us) rating.
