That margin — 11.1 V standoff to 18.2 V clamp — gives a 12 V supply enough headroom to ride through load-dump and inductive kickback without stressing downstream silicon. Peak pulse power of 1500 W (1.5 kW) is specified for the standard 10/1000 µs exponential waveform — this is the industry benchmark for TVS surge rating. The 82.4 A peak pulse current at the clamping voltage tells you the diode can absorb a high-energy transient without failing short, which is the failure mode that takes out the protected load. Operating junction temperature spans -65°C to 150°C, covering the full automotive under-hood and engine-bay thermal profile. The wide range also suits outdoor telecom enclosures where ambient swings from deep freeze to solar loading. ## DO-214AB (SMC) surface-mount package Housed in the DO-214AB (SMC) package, the diode is a surface-mount device that reflows alongside standard passives. The SMC body footprint is larger than the smaller SMA/SMB siblings, which means the copper pad area under the terminals dissipates heat more effectively — relevant when repetitive pulses raise the average junction temperature. The base product number is 1.5SMC13, so the same die and package are shared across the unidirectional and bidirectional variants in this voltage bin.","metaTitle":"1.5SMC13CAHM3_A/H Vishay TVS Diode, 1.5kW Bidirectional","metaDescription":"Vishay 1.5SMC13CAHM3_A/H automotive AEC-Q101 TVS, 11.1V standoff, 18.2V clamp, 1.5kW peak pulse.
