Housed in a DO-201AA (DO-27) axial leaded package with a DO-201 supplier device package designation, the through-hole mounting suits point-to-point wiring and high-reliability solder joints in high-vibration environments. ## No power line protection — pure signal and bus transient suppression The 1.5KE15CH does not include power line protection circuitry — it is designed for general-purpose transient suppression on signal, data, and low-power bus lines where the 12.1V standoff voltage provides margin below the 13.5V minimum breakdown. For a 12V automotive battery line, the 12.1V standoff sits below the normal operating voltage range (typically 9V to 16V), so the diode remains non-conducting during normal operation and only clamps above 13.5V.","metaTitle":"1.5KE15CH TVS Diode, 1.5kW Bidirectional, DO-201, AEC-Q101","metaDescription":"Taiwan Semiconductor 1.5KE15CH Zener TVS diode, 1500W peak pulse power, 12.1V standoff, 71A Ipp, bidirectional, DO-201AA axial, AEC-Q101 automotive grade.","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":"1.5KE15","Operating Temperature":"-55°C ~ 175°C (TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Voltage - Breakdown (Min)":"13.5V","Voltage - Clamping (Max) @ Ipp":"22V","Voltage - Reverse Standoff (Typ)":"12.1V","Current - Peak Pulse (10/1000µs)":"71A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2712","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5eaf730ddee2c93195d8150640448844.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the 1.5KE15CH's clamping performance at peak pulse current?","answer":"At the 71A peak pulse current (10/1000µs waveform), the maximum clamping voltage is 22V.
