Product details

Automotive transient protection — AEC-Q101 qualified

The 1.5KE110CAHE3/51: It clamps a 94V normal line to 152V maximum at 9.9A peak pulse current, protecting downstream electronics from inductive load dumps, lightning-induced surges, and switching transients.

Package and board-fit — axial through-hole

No polarity marking needed — simplifies pick-and-place and reduces assembly errors.

Sourcing reality — obsolete, no official successor

Vishay has marked the 1.5KE110CAHE3/51 as obsolete. No official successor order code is recorded from the manufacturer. The base product number 1.5KE110 identifies the electrical rating family (110V breakdown class). Other variants in the TransZorb series share the same DO-201AA footprint and 1500W rating, but only this suffix carries the AEC-Q101 automotive qualification. A non-automotive substitute may fit the PCB but fails the PPAP documentation requirement for a production vehicle.

Frequently asked questions

How can I source the 1.5KE110CAHE3/51 for a BOM line?

We source this obsolete part through independent surplus and broker distribution. Pricing and availability are confirmed at the time of your RFQ against the required quantity.

What compliance documentation does Vishay provide for the 1.5KE110CAHE3/51?

The part carries AEC-Q101 automotive qualification. RoHS and REACH compliance are standard for this series; the specific certificate is available from Vishay's documentation portal.
