Product details

Package and thermal envelope

The 1.5KE6.8CA-B: Housed in a DO-201AA (DO-27) axial-lead through-hole package, with the supplier device package designated as DO-201. The through-hole format suits point-to-point wiring, terminal blocks, or PCB mounting where a robust mechanical anchor is preferred over surface-mount. The wide temperature margin ensures the clamping voltage and leakage current remain within spec across the application's ambient extremes.

Production status and supply posture

Littelfuse lists the 1.5KE6.8CA-B as Active.
