That is the design target for ECU input protection on unswitched rails. The breakdown minimum of 6.45V sits close enough above the 5.8V standoff that the TVS stays invisible on a 5V rail under normal conditions, then turns hard on and clamps the spike before it reaches the protected node. The ±5% tolerance band is tight enough to make this prediction reliable across production. ## AEC-Q101 qualification and the under-hood temperature envelope AEC-Q101 is the automotive discrete-semiconductor stress qualification — it means the part passed temperature cycling, humidity bias, and peak pulse current life testing at the grades a Tier-1 supplier requires before an ECU goes into a production vehicle. ## DO-214AB SMC package — automotive TVS footprint The DO-214AB SMC is the dominant automotive TVS package — it tolerates the reflow profiles used in ECU board assembly and the thermal cycling that follows in field service. Surface-mount termination supports automated placement at the speeds production lines run. Availability and current pricing confirmed at RFQ; no stock-holding claim is made here for an independent-channel part.","metaTitle":"Vishay 1.5SMC6.8CAHE3/9AT TVS Diode, 1500W, 6.45V","metaDescription":"Vishay 1.5SMC6.8CAHE3/9AT bidirectional TVS diode, AEC-Q101 automotive, 1500W peak pulse, 6.45V min breakdown, DO-214AB SMC.
