The DO-214AB (SMC) package supports reflow assembly and carries the same footprint as other 1.5SMC devices, so a single PCB layout can accommodate a range of standoff voltages across the family. ## AEC-Q101 qualification and temperature range The -65°C to +150°C junction temperature range covers underhood and engine-bay thermal profiles with margin. The series designation includes TransZorb® — Vishay's trademark for silicon-avalanche TVS diodes designed for repetitive surge handling without performance degradation. ## Sourcing and compliance posture The base product number is 1.5SMC15; the full order code includes the suffix that denotes the AEC-Q101 automotive grade and tape-and-reel packaging. RoHS and REACH compliance documentation is available from Vishay upon request.","metaTitle":"1.5SMC15AHM3/I Vishay TVS Diode, 1500W, DO-214AB, AEC-Q101","metaDescription":"Active Vishay 1.5SMC15AHM3/I Zener TVS diode, 1500W peak pulse, 12.8V standoff, AEC-Q101 qualified.
