Device identity and key parametrics
The 1.5SMC110CAHE3/57T: The reverse standoff voltage is 94 V, with a minimum breakdown of 105 V — so a 94 V nominal rail sees clamping starting just above that threshold. A single bidirectional channel means one device protects a signal pair; the DO-214AB (SMCJ) surface-mount package handles the 1500 W pulse without derating at 25 °C.
Where this TVS fits in a design
AEC-Q101 qualification targets automotive electronic control units, battery management systems, and sensor modules that must survive load-dump and ISO 7637-2 transients on the 12 V or 24 V bus. The 94 V standoff covers the nominal rail with margin for steady-state ripple. The -65 °C to 150 °C junction temperature range suits under-hood and engine-bay placement where ambient temperatures exceed 105 °C. Surface-mount DO-214AB (SMC) footprint is standard for TVS diodes in this power class — the copper pad area on the PCB directly sets the thermal resistance for pulse dissipation.
