The 19 V clamping ceiling limits the voltage seen by the load during a surge event. ## Obsolete — sourcing through independent channels Vishay has marked the 1.5KE13CHE3/73 as obsolete.","metaTitle":"1.5KE13CHE3/73 Vishay Zener TVS, 1500W, Bidirectional","metaDescription":"Vishay 1.5KE13CHE3/73 Zener TVS diode, 1500W peak pulse, 10.5V standoff, bidirectional, AEC-Q101, DO-201AA axial.
