This is a standard footprint found on countless telecom, industrial, and power-supply boards — the replacement fits the same drilled holes and solder pads without a layout change. ## Obsolete — sourced through independent channels Vishay has marked the 1.5KE220-/73 as obsolete. ## -55 to 175 °C — industrial and high-temp environments The junction temperature range spans -55 to 175 °C, covering most industrial, automotive under-hood, and telecom outdoor cabinet conditions. The wide margin above 125 °C means the device handles self-heating during repetitive surge events without immediate derating.","metaTitle":"Vishay 1.5KE220-E3/73 TransZorb TVS, 1500W, 175V Standoff","metaDescription":"Obsolete Vishay 1.5KE220-E3/73 TransZorb Zener TVS diode, 1500W peak pulse, 175V reverse standoff, 344V clamping.","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":"1.5KE220","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"198V","Voltage - Clamping (Max) @ Ipp":"344V","Voltage - Reverse Standoff (Typ)":"175V","Current - Peak Pulse (10/1000µs)":"4.4A"}},"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 1.5KE220-/73 come in?","answer":"It is supplied in a DO-201AA (DO-27) axial leaded through-hole package.
