114V reverse standoff, 1500W peak pulse — what this Zener TVS handles
The 1N6170AUS is a bidirectional Zener TVS diode from Microchip Technology, designed to clamp transients on a 114 V nominal rail. With a peak pulse power rating of 1500 W, it absorbs energy from lightning-induced surges, inductive load switching, or ESD events without sacrificing the protected circuit. The minimum breakdown voltage is 142.5 V, and the clamping voltage at the peak pulse current of 7.3 A is 206.3 V max. This means the downstream components must withstand at least 206.3 V for the duration of the surge — a typical margin for 114 V bus protection in industrial or telecom equipment.
