Product details

Obsolete — sourcing through independent channels

Vishay has marked the 1.5KE7.5AHE3/51 as obsolete. No official successor is listed.

AEC-Q101 qualification and automotive deployment

The operating temperature range spans -55°C to 175°C, covering the full automotive ambient envelope from cold-crank to engine-bay heat soak.

Through-hole axial package

Housed in a DO-201AA / DO-27 axial leaded package, the 1.5KE7.5AHE3/51 mounts through-hole — suitable for point-to-point wiring or PCB layouts where the lead bend radius and hole diameter match the 0.042-inch lead diameter. Bulk packaging means loose tubes or bag, not tape-and-reel.

Frequently asked questions
