1500 W peak pulse in a DO-214AB footprint
The 1.5SMC11AHM3_A/H: The 9.4 V reverse standoff voltage places it on 12 V nominal rails where the clamping threshold at 15.6 V (max) keeps downstream silicon inside the absolute-max rating during a load-dump or inductive kickback event.
AEC-Q101 qualification for under-hood deployment
This part carries AEC-Q101 automotive qualification, meaning it has passed the reliability stress tests (temperature cycling, HTRB, H3TRB) required for engine-bay and chassis-domain electronics. The operating temperature range spans -65 °C to 150 °C junction, covering the full automotive temperature envelope with margin for self-heating under repetitive surge conditions. The DO-214AB (SMC) package is a standard surface-mount footprint for 1.5 kW-class TVS diodes. The copper pad area under the cathode tab sets the thermal resistance to the board; a 600 mm² pad on 2 oz copper keeps the junction temperature rise within the 150 °C limit at rated pulse power.
