At a 48V nominal rail, that gives roughly 37.5V of headroom to the clamping ceiling under surge conditions. ## Sourcing the 1.5SMCJ48 No official cross-reference or second-source alternative is listed in the record for this specific order code.","metaTitle":"Diotec 1.5SMCJ48 TVS Diode, 48V standoff, 1500W","metaDescription":"Diotec 1.5SMCJ48 unidirectional Zener TVS diode, 48V standoff, 85.5V clamping, 1500W peak pulse, DO-214AB SMC surface mount.
