Breakdown triggers at 33.3 V minimum, clamping the transient event. The 53.5 V maximum clamping voltage at 28 A peak pulse is what the downstream load actually sees during a surge — that number determines whether your downstream semiconductors survive. ## General-purpose TVS — where it sits in the protection hierarchy Diotec lists this as General Purpose and explicitly flags Power Line Protection: No — the part is suited for secondary-side protection on signal rails, control lines, and low-current distribution rather than at the AC mains input where higher energy ratings are required. The 30 V standoff fits 24 V industrial control rails comfortably with margin. ## Sourcing and lifecycle posture The 1.5SMCJ30 is listed Active by Diotec Semiconductor.","metaTitle":"1.5SMCJ30 Zener TVS Diode, 30V standoff, 1.5kW peak","metaDescription":"Diotec Semiconductor 1.5SMCJ30 unidirectional Zener TVS, 30V reverse standoff, 1.5kW peak pulse, 53.5V clamping.
