Breakdown kicks in no lower than 71.3 V min, and during a surge the clamping voltage at the peak pulse current does not exceed 104 V max. That roughly 40 V window between standoff and clamping is where the downstream circuitry sees protection headroom during automotive load-dump or inductive dump transients. Peak pulse current at that same waveform is 14.6 A. Verify your surge waveform matches the 10/1000 µs shape; a faster or slower transient changes the energy the part sees. ## Junction temperature and the automotive thermal envelope Junction operating range runs to 150°C, starting at -65°C. That covers the under-hood profile — engine-bayECU, chassis-node, and 24V commercial-vehicle rails all sit within that window. The AEC-Q101 qualification means the part passed the temperature-cycle, bias, and power-temperature stress screens required for automotive safety-critical deployments.","metaTitle":"1.5SMC75CAHE3/57T TVS Diode, 64.1V Standoff, AEC-Q101","metaDescription":"Vishay 1.5SMC75CAHE3/57T bidirectional TVS Zener, 64.1V standoff, 104V clamping, 1500W peak pulse, AEC-Q101 qualified.
