Product details

Automotive-grade transient suppression for 12V rails

The Vishay 1.5KE7.5AHE3_A/D is a 1500 W peak-pulse-power TransZorb TVS diode in the AEC-Q101-qualified automotive series, designed to clamp transients on 6.4 V nominal rails — a common protection target for 12 V battery-fed electronics where the regulated supply sits around 5 V or 6 V.

Clamping and breakdown characteristics

The 6.4 V reverse standoff voltage means the diode does not conduct at the normal rail voltage, only during an overvoltage event — a clean fit for 5 V or 6 V supply rails where leakage must be minimal under steady-state conditions.

Frequently asked questions

What is the closest pin-compatible alternative to 1.5KE7.5AHE3_A/D in this Circuit Protection family?

The base product number 1.5KE7.5 covers the same DO-201AA package and 1500 W rating; the AHE3 suffix denotes the AEC-Q101 automotive qualification. A non-automotive sibling (1.5KE7.5A) is functionally identical but lacks the automotive stress screening — use the AHE3 variant for production builds that require AEC-Q101 traceability.

What compliance documentation does Vishay provide for 1.5KE7.5AHE3_A/D?

As an AEC-Q101 qualified device, Vishay supplies PPAP documentation and a certificate of compliance upon request. The part is RoHS-compliant; the specific RoHS and REACH declarations are available in the manufacturer's compliance database.

Who supplies 1.5KE7.5AHE3_A/D and how is it quoted for volume purchases?
