It clamps transients on a 30.8V nominal rail to 49.9V maximum while conducting 30.1A of peak pulse current (10/1000 µs waveform). ## Protection window and bidirectional layout The reverse standoff voltage of 30.8V means the diode draws negligible leakage below that rail level. Breakdown starts at 34.2V minimum, and clamping is guaranteed at 49.9V maximum — a 15.7V window from standoff to clamp that keeps downstream silicon inside its safe operating area for most 36V-rated parts. A single bidirectional channel protects both polarities, simplifying layout on AC-coupled signals or bipolar supplies where two unidirectional diodes in anti-series would otherwise be needed. ## Obsolete — sourcing through independent channels Vishay has marked the 1.5KE36CAHE3/51 as obsolete. Available through independent surplus and excess inventory channels. Quantities are lot-specific; pricing and lead time are confirmed at RFQ. The axial DO-201AA footprint is common across the 1.5KE series, so a functional cross to an active unidirectional or different voltage variant may require a board spin.","metaTitle":"1.5KE36CAHE3/51 Vishay TVS, 1500W, 30.8V Standoff, DO-201AA","metaDescription":"Vishay 1.5KE36CAHE3/51 TransZorb TVS, 1500W peak pulse, 30.8V standoff, bidirectional, AEC-Q101.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Vishay General Semiconductor - Diodes Division","Type":"Zener","Series":"Automotive, AEC-Q101, TransZorb®","Package":"Bulk","Applications":"Automotive","Mounting Type":"Through Hole","Package / Case":"DO-201AA, DO-27, Axial","Product Status":"Obsolete","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE36","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Voltage - Breakdown (Min)":"34.2V","Voltage - Clamping (Max) @ Ipp":"49.9V","Voltage - Reverse Standoff (Typ)":"30.8V","Current - Peak Pulse (10/1000µs)":"30.1A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5346","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/55e3e40e24fd2c3f96443c3e231bf459.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest alternative to 1.5KE36CAHE3/51 in the same family?","answer":"No official pin-compatible successor is documented.
