The breakdown voltage of 71.3 V minimum is where the TVS first begins to conduct, steering the transient away from the load. At the rated peak current of 14.6 A the clamping voltage is held to a maximum of 104 V, so downstream circuits see a defined voltage ceiling rather than the raw transient amplitude. ## Package and thermal environment The DO-214AB (SMC) is the standard surface-mount footprint for 1.5 kW TVS diodes — the cathode bar on the package underside is the primary thermal path to the board pad. A generous copper landing under the tab and thermal via connectivity to inner ground planes carry the clamped surge energy away from the junction. The operating junction temperature range of -65 to 150 C covers the full span from cold-start environments to thermal soak in enclosed equipment, and the datasheet derating curve shows the usable peak pulse power collapses above approximately 25 C case temperature — that is the sizing constraint for protected rails in hot environments. ## Active sourcing posture Listed Active by Vishay General Semiconductor — Diodes Division. Sourced to order against BOM quantity through independent distribution with availability and current lead time confirmed at RFQ.","metaTitle":"Vishay 1.5SMC75CA-E3/9AT TVS, 1.5kW, 71.3V Breakdown","metaDescription":"Vishay 1.5SMC75CA-E3/9AT bidirectional Zener TVS diode, 1500 W peak pulse, 71.3 V min breakdown, -65 to 150 C junction.
