The absence of power line protection means this part is intended for secondary-side or signal-level clamping, not for direct AC mains primary-side surge suppression. ## Obsolete — sourcing through independent channels Vishay has marked the 1.5KE15-/73 as obsolete.","metaTitle":"Vishay 1.5KE15-E3/73 TransZorb TVS, 1500W, 12.1V Standoff","metaDescription":"Obsolete Vishay 1.5KE15-E3/73 TransZorb TVS diode, 1500W peak pulse, 12.1V reverse standoff, 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 & 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":"1.5KE15","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"13.5V","Voltage - Clamping (Max) @ Ipp":"22V","Voltage - Reverse Standoff (Typ)":"12.1V","Current - Peak Pulse (10/1000µs)":"68.2A"}},"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 is the 1.5KE15-/73 used for?","answer":"It is a 1500W TransZorb TVS diode that clamps transient overvoltages on a 12V DC rail.
