The reverse standoff voltage of 15.3 V sets the maximum DC operating voltage on the protected line without drawing leakage current. For a 12 V automotive rail with a 15.3 V TVS, the diode stays out of the circuit during normal operation and only conducts when a transient exceeds the 17.1 V minimum breakdown threshold. ## AEC-Q101 qualification — built for the under-hood temperature band That is the under-hood automotive band — an ECU, BMS, or headlamp driver that sees 125°C ambient on a hot engine still has margin before the junction hits its 150°C absolute limit. The DO-214AB (SMC) surface-mount package is the standard footprint for 1500 W TVS diodes. The copper pad area under the cathode tab sets the thermal resistance to the board — a solid ground-plane connection pulls heat out of the junction during repetitive surge events.","metaTitle":"1.5SMC18AHM6G TVS Diode, 1500W, AEC-Q101, DO-214AB","metaDescription":"1.5SMC18AHM6G Zener TVS diode, 1500W peak pulse power, 15.3V standoff, AEC-Q101 qualified.
