Product details

Part identity and key ratings

The 1.5KE10CHE3/54: The bidirectional design means a single device protects both polarities, simplifying board layout for automotive transient suppression on 12V rails.

Vishay has marked the 1.5KE10CHE3/54 as obsolete. No official successor order code is recorded, so replacement sourcing relies on independent distribution channels.

What the clamping ratings mean for the BOM

The 8.1V reverse standoff voltage means the diode does not conduct at normal 12V system levels, but clamps at 15V maximum under surge — protecting downstream electronics from load-dump and inductive kickback transients. The 100A peak pulse current rating (10/1000 µs) covers high-energy events typical in automotive environments.

Frequently asked questions

Where can I buy 1.5KE10CHE3/54 and get a price?

Submit an RFQ for current availability and pricing — no stock or price figures are held on this listing.

What is the closest pin-compatible alternative to 1.5KE10CHE3/54?

A functional replacement must match the 1500W pulse rating, 8.1V standoff, bidirectional configuration, and DO-201AA package. Confirm the replacement's AEC-Q101 qualification if automotive-grade compliance is required.
