Product details

The 1.5KE6.8: The 5.8 V reverse standoff voltage means it begins clamping above the normal 5 V rail tolerance, protecting downstream silicon from transients up to 11.03 V clamping at 144.8 A peak pulse current.

Obsolete — sourcing through independent distribution

Littelfuse lists the 1.5KE6.8 as Obsolete. For BOM continuity, the 1.5KE series includes other voltage variants in the same DO-201 package, but a direct pin-compatible replacement with identical 5.8 V standoff and 1500 W rating would require a parametric search — no drop-in substitute is documented.
