Product details

What this TVS diode covers

The 1.5KE7.5CHE3/54: The DO-201AA axial leaded package (also known as DO-27) is through-hole mounted — straightforward to replace on a board with plated through-holes, no hot air needed. The single bidirectional channel means it protects against both positive and negative transients, which is typical for automotive load-dump or inductive kickback scenarios.

Vishay lists this part as obsolete. No pin-compatible direct replacement is documented by Vishay, so a board-level alternative search (matching 1500 W, 6.05 V standoff, bidirectional, DO-201AA) is the practical path for new designs.

Frequently asked questions

What is the closest pin-compatible alternative to 1.5KE7.5CHE3/54?

For a drop-in replacement, look for a bidirectional TVS diode in DO-201AA with 1500 W peak pulse, 6.05 V standoff, and AEC-Q101 qualification. Parametric search on those four criteria will yield candidates from other brands.
