Breakdown occurs at a minimum of 20V, and the clamping voltage is held to 29.2V at the rated peak pulse current of 51.4A — the downstream circuitry must survive that clamp voltage for the pulse duration. ## Active production, sourced per RFQ ## Temperature range and mounting note Rated for junction temperatures from -65°C to 150°C, covering industrial and some military-ambient environments.","metaTitle":"SMCJ18AE3/TR13 – Microchip 1.5kW Zener TVS, 18V Standoff","metaDescription":"Active-production Zener TVS diode, 1500W peak pulse, 18V reverse standoff, 29.2V clamp at 51.4A.
