The TransZorb® silicon-avalanche construction delivers a tight clamping ratio — the 246V clamp at 6.1A is only 1.44× the 171V breakdown, which keeps the protected rail within the safe operating area of downstream ICs rated for 250V or higher. The DO-214AB (SMC) package measures roughly 7.1 mm × 6.2 mm with a 2.4 mm seated height. The large copper tab on the cathode side (for unidirectional parts) or the body itself (for bidirectional) conducts heat into the PCB copper — a 25 mm² pad per terminal keeps the junction temperature rise within limits for repetitive surges. The base product number is 1.5SMC180, and the full suffix encodes the bidirectional (CA), automotive grade (HE3), and reel packaging (9AT).","metaTitle":"Vishay 1.5SMC180CAHE3/9AT TVS, 1.5kW, 154V, DO-214AB","metaDescription":"Vishay 1.5SMC180CAHE3/9AT bidirectional TVS diode, 1500W peak pulse power, 154V reverse standoff, AEC-Q101 qualified.
