For a 24 V nominal bus, the clamp margin is roughly 10 V above the rail — tight enough to protect downstream silicon rated for 40 V or higher. ## Package and deployment envelope Housed in a DO-201AA / DO-27 axial-lead package, through-hole mounted. The operating junction temperature range spans -55°C to 175°C, covering industrial and military-grade thermal environments — outdoor telecom cabinets, motor drive DC buses, and power supply input stages. Single unidirectional channel — polarity matters in the layout. The cathode band on the package must face the positive rail; reverse insertion defeats the protection.","metaTitle":"Vishay 1.5KE24-E3/54 TransZorb TVS, 1500W, 34.7V Clamp","metaDescription":"Vishay 1.5KE24-E3/54 Obsolete TransZorb Zener TVS, 1500W peak pulse, 34.7V clamping, DO-201AA axial.","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":"TransZorb®","Package":"Tape & Reel (TR)","Applications":"General Purpose","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":"1.5KE24","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"21.6V","Voltage - Clamping (Max) @ Ipp":"34.7V","Voltage - Reverse Standoff (Typ)":"19.4V","Current - Peak Pulse (10/1000µs)":"43.2A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cbd949ebcf4c95d5b4ea8fdecf87536f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What package does the 1.5KE24-/54 use?","answer":"DO-201AA / DO-27 axial-lead, through-hole mount.
