Product details
Frequently asked questions
What compliance documentation does Vishay provide for 1.5SMC39CAHE3/9AT?
The AEC-Q101 qualification is the primary automotive compliance standard on record. Vishay's TransZorb series is RoHS-compliant per the standard HE3 suffix designation. For PPAP, IMDS, or full AEC-Q101 test report requests, the qualification data package is available through Vishay's automotive documentation portal.
What is the 1.5SMC39CAHE3/9AT's clamping performance for a 24 V automotive bus?
The reverse standoff voltage is 33.3 V, so it sits idle below the nominal 24 V rail. Breakdown occurs at a minimum of 37.1 V. For a 24 V bus transient that reaches 60 V, the TVS clamps to 53.9 V, protecting downstream 60 V-rated silicon with margin.
