This clamping ceiling defines the voltage stress the downstream components see during a surge event — if the protected device's absolute maximum rating is below 70 V, this TVS may not provide enough margin. ## Lifecycle: active, no LTB risk Microchip lists the 1N6123AUS/TR as Active.","metaTitle":"1N6123AUS/TR Zener TVS Diode – 500W, 48.5V Breakdown","metaDescription":"Microchip 1N6123AUS/TR Zener TVS, 500W peak pulse, 48.5V breakdown, 38.8V standoff, bidirectional, SQ-MELF B, active production.
