The 1.5KE body size is standard for 1500W TVS diodes — the lead spacing and body diameter match common PCB footprints for this power class. The bidirectional configuration uses a single device for symmetrical clamping on AC or bipolar signal lines, eliminating the need for two back-to-back unidirectional diodes. For existing BOM lines, the 1.5KE47CHE3/54 remains a drop-in fit where the DO-201AA footprint and 1500W peak pulse rating are specified.","metaTitle":"Vishay 1.5KE47CHE3/54 TVS Diode, 1500W, Bidirectional","metaDescription":"Obsolete Vishay 1.5KE47CHE3/54 automotive TVS diode, 1500W peak pulse, 38.1V standoff, AEC-Q101, DO-201AA axial.
