No power line protection feature means it is designed for data/signal lines or low-power auxiliary rails, not the main power feed. Qualified to AEC-Q101, the automotive discrete semiconductor stress test standard — this covers temperature cycling, high-temperature reverse bias, and ESD robustness. The -65°C to 150°C junction temperature range matches engine-bay and under-hood thermal profiles, as well as outdoor telecom cabinet environments. The DO-214AB (SMC) surface-mount package is the standard footprint for 1500W TVS diodes. The large copper tab on the cathode side (for unidirectional parts) or the body itself (bidirectional) conducts heat into the PCB copper pour — the board layout's thermal pad area directly sets the derating at elevated ambient temperatures. ## Active lifecycle — no end-of-life pressure The AEC-Q101 traceability chain is maintained through the supply lot documentation.","metaTitle":"1.5SMC120CAHM3/H TVS Diode, 1500W, Bidirectional, DO-214AB","metaDescription":"Vishay 1.5SMC120CAHM3/H bidirectional TVS, 1500W peak pulse, 102V standoff, AEC-Q101.
