Its 29.1 V reverse standoff voltage sits above the steady-state rail, while the 32.4 V minimum breakdown triggers clamping before the downstream electronics see damage. ## Clamping Performance and Pulse Handling The 1500 W rating assumes the standard 10/1000 µs pulse; shorter pulses (8/20 µs) allow higher peak current before the junction temperature limit is reached. The single unidirectional channel protects one rail polarity. For bidirectional clamping on AC-coupled or bipolar lines, two devices back-to-back or a dedicated bidirectional TVS would be needed. ## Obsolete Status and Sourcing Reality Availability and pricing are confirmed at RFQ against the required quantity. The DO-201AA axial package is a common footprint, so parametric equivalents from other manufacturers (same standoff voltage and peak power) can be evaluated as functional replacements, though a board spin is not required if the replacement shares the same package outline.","metaTitle":"Vishay 1.5KE36HE3/54 Zener TVS, 1500W, AEC-Q101","metaDescription":"Vishay 1.5KE36HE3/54 Zener TVS diode, 1500W peak pulse, 29.1V standoff, AEC-Q101 qualified.
