Reverse standoff voltage is 17.8 V, meaning the diode draws negligible leakage below that rail level. Breakdown is guaranteed between 19.8 V and the clamp threshold, so a 12 V or 15 V bus stays below the standoff during normal operation and the TVS only conducts when the transient exceeds the breakdown knee. ## DO-201 axial — board-fit and procurement note The DO-201AA (DO-27) axial-lead package is a through-hole form factor with a 0.052-inch diameter lead. It fits standard 1.0 mm drilled plated-through holes and is hand-solderable or wave-solderable. The bidirectional configuration means a single device clamps both polarities — no series arrangement needed — which saves one component and one hole pair per protected line.","metaTitle":"1.5KE22CH TVS Diode, 1500W, 17.8V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE22CH bidirectional Zener TVS, 1500W peak pulse, 17.8V reverse standoff, AEC-Q101 qualified, DO-201 axial.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Taiwan Semiconductor Corporation","Type":"Zener","Grade":"Automotive","Series":"1.5KE","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Through Hole","Qualification":"AEC-Q101","Package / Case":"DO-201AA, DO-27, Axial","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE22","Operating Temperature":"-55°C ~ 175°C (TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Voltage - Breakdown (Min)":"19.8V","Voltage - Clamping (Max) @ Ipp":"31.9V","Voltage - Reverse Standoff (Typ)":"17.8V","Current - Peak Pulse (10/1000µs)":"49A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2712","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ee98a36af2d41af2ff4cfdd2155fed9e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What automotive qualification does the 1.5KE22CH carry?","answer":"The device is AEC-Q101 qualified with an Automotive grade.
