The DO-214AB (SMC) surface-mount package fits standard pick-and-place assembly, and the -65°C to 150°C junction temperature range covers under-hood and telecom cabinet thermal profiles. ## Clamping voltage and pulse current — what they mean for your rail With a 274 V maximum clamping voltage at the 5.5 A peak pulse current, this diode limits transients on a 171 V bus to a level that downstream semiconductors rated for 300 V can survive. The unidirectional Zener construction (single channel) means the cathode is the protected rail; the anode connects to ground. For AC or bidirectional protection, two devices back-to-back or a dedicated bidirectional TVS is needed. ## AEC-Q101 qualification and active lifecycle The base product number 1.5SMC200 indicates the family; the HM3/H suffix denotes the automotive-grade, halogen-free, RoHS-compliant version.","metaTitle":"Vishay 1.5SMC200AHM3/H TVS Zener, 1500W, DO-214AB","metaDescription":"Vishay 1.5SMC200AHM3/H Zener TVS, 1500W peak pulse, 274V clamp, AEC-Q101 automotive grade, DO-214AB.
