The 15V clamping voltage at 100A peak pulse current limits the voltage spike seen by downstream components. The 8.1V reverse standoff voltage means the diode draws negligible leakage current below that DC level — it stays invisible on the rail during normal operation. ## Obsolete — sourced through surplus channels Marked obsolete by Vishay. Available through independent distribution — quantities are lot-specific, date codes vary per inventory batch. ## DO-201AA axial package — through-hole mounting Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE10-/73 mounts through-hole on the PCB. The large body and thick leads handle the thermal pulse from a 1.5kW surge without exceeding the 175°C junction limit. Supplied in Tape & Box (TB) — suitable for hand-insertion or selective-wave solder assembly. No power line protection feature (the device is a unidirectional TVS, not a bidirectional or rail-clamp array).","metaTitle":"1.5KE10-E3/73 Vishay TransZorb TVS, 1.5kW, 15V Clamp","metaDescription":"Obsolete Vishay 1.5KE10-E3/73 TransZorb Zener TVS diode, 1.5kW peak pulse, 15V clamping, DO-201AA.","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 & Box (TB)","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":"1.5KE10","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"9V","Voltage - Clamping (Max) @ Ipp":"15V","Voltage - Reverse Standoff (Typ)":"8.1V","Current - Peak Pulse (10/1000µs)":"100A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cbd949ebcf4c95d5b4ea8fdecf87536f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the 1.5KE10-/73 obsolete?","answer":"Yes, Vishay has marked the 1.5KE10-/73 as obsolete.
