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.","metaTitle":"Littelfuse 1.5KE9.1 TVS Diode, 1500W, DO-201","metaDescription":"Littelfuse 1.5KE9.1 Zener TVS diode, 1500W peak pulse power, 7.78V standoff, DO-201 axial.
