The 19.8 V minimum breakdown voltage ensures the device starts clamping before the rail exceeds the downstream IC's abs-max rating. ## Automotive grade and package fit The DO-201AA (DO-27) axial-lead package fits standard through-hole PCB layouts. The 1.5KE package footprint is shared across the series, so a board designed for a 1.5KE22A accepts this part without layout changes. ## Obsolete — sourcing through independent channels Vishay lists the 1.5KE22CHE3/73 as obsolete. A cross-reference to a different Vishay TVS with the same 17.8 V standoff and 1500 W rating may exist, but no pin-compatible replacement is documented in the official record.","metaTitle":"1.5KE22CHE3/73 Vishay TVS Zener, 1500W, DO-201AA","metaDescription":"Obsolete 1.5KE22CHE3/73 Vishay TVS Zener diode, 1500W peak pulse, 17.8V standoff, AEC-Q101.
