At 1.5 kW peak pulse the device absorbs the energy of a fast transient without degradation — the 150 °C junction temperature rating gives headroom during repeated clamping events, so a board that sees occasional inductive kick or ESD has thermal margin built into the spec rather than requiring a derate on first event. ## What the standoff and breakdown voltages mean for rail protection The 6.4 V reverse standoff is the working rail the diode monitors — it sits reverse-biased below that voltage and conducts only when a transient pushes the rail above it. The 7.13 V minimum breakdown ensures the clamping action activates above the nominal rail plus reasonable tolerance — a 5 V or 5.2 V rail has plenty of margin to the 7.13 V floor, so normal operation at 6.4 V standoff stays clean without leakage false-triggering. ## SMC package and sourcing context The DO-214AB (SMCJ) package is the standard foot for this series — any pin-compatible 1.5SMC CA-variant in the same case size drops in, which matters when you are chasing spot market availability on a fast-turn build.","metaTitle":"Vishay 1.5SMC7.5CA-M3/57T TVS Diode, 6.4V, 1.5kW, DO-214AB","metaDescription":"Vishay 1.5SMC7.5CA-M3/57T bidirectional TVS diode, 6.4V standoff, 11.3V clamping, 1.5kW peak pulse, DO-214AB SMC.
