The standoff voltage of 64.1 V typ defines the working rail the diode monitors without conduction — the protected node sits below this in normal operation. ## Automotive grade and thermal margin Junction temperature rating is -65 to 150 °C. In an engine-compartment or chassis-domain layout the board-level ambient can reach 125 °C; the 150 °C Tj ceiling gives headroom above the typical automotive Grade 1 limit of 125 °C, so the part survives the upper end of the temperature band without derating below the rated peak pulse current. The \"CA\" suffix denotes bidirectional polarity; the \"HE3\" suffix is the Vishay halogen-free / RoHS-compliant AEC-Q101 grade designator for this series. The supplier device package field lists DO-214AB (SMCJ) — the SMC and SMCJ designations are the same outline; confirm the land pattern matches the board pad definition for the DO-214AB land pattern in the applicable IPC standard. Packaged as tape and reel — the standard orientation for automated SMT pick-and-place on high-volume automotive board assembly lines. Listed Active by Vishay General Semiconductor — Diodes Division. The part is sourced to order; availability and lead time confirmed at RFQ. For automotive qualification programs requiring PPAP or IATF 16949 documentation, the component's AEC-Q101 qualification package is sourced through the manufacturer directly.","metaTitle":"Vishay 1.5SMC75CAHE3/9AT TVS Diode, 1500W Peak, AEC-Q101","metaDescription":"Vishay 1.5SMC75CAHE3/9AT bidirectional TVS Zener, 71.3V min breakdown, 104V clamping, 14.6A peak pulse, AEC-Q101 automotive.
