Minimum breakdown is 44.7V, clamping at 64.6V max — a 44% headroom above the 35.8V standoff. That margin keeps the protected rail below the absolute-max rating of most 48V bus transceivers and 40V-rated DC-DC converters during a surge event. The SQ-MELF package also offers lower thermal resistance than a comparable SMB/SMC plastic body, which helps keep junction temperature in check during sustained clamping. The SQ-MELF package is a standard Microchip offering, so lead times typically track the broader TVS product line.","metaTitle":"1N6158AUS Zener TVS Diode 1500W SQ-MELF Active Microchip","metaDescription":"1N6158AUS bidirectional Zener TVS diode, 1500W peak pulse power, 35.8V standoff, SQ-MELF package, -55°C to 175°C.
