Product details

The 1.5KE9.1: The DO-201AA (DO-27) axial-lead package suits through-hole mounting on boards where a robust mechanical anchor is preferred over surface-mount.

Obsolete — sourcing through independent channels

Littelfuse lists the 1.5KE9.1 as Obsolete. No official successor or second-source order code is published. The 1.5KE series is a broad TVS family; a parametric search for a Zener TVS with similar standoff voltage (7.78 V) and peak pulse power (1500 W) in a DO-201 package may yield a functionally equivalent alternative, but no pin-compatible drop-in replacement is recorded from Littelfuse.
