AEC-Q101 qualified 1.5 kW TVS for 12 V automotive buses
The 1.5SMC10CAHE3/9AT: The 1500 W pulse rating at 103 A peak current gives enough margin for most 12 V system surges without needing a larger package.
Breakdown and clamping — where the protection window sits
The breakdown voltage range starts at 9.5 V minimum, so the diode begins conducting before the protected rail exceeds typical 12 V tolerances. With a maximum clamp of 14.5 V at 103 A, downstream components rated for 16 V see a safe stress level even during worst-case surge events.
The -65°C to +150°C junction temperature range covers under-hood automotive environments and high-reliability industrial applications. The operating temperature envelope is wide enough that derating is driven by the PCB thermal design, not the die itself.
