AEC-Q101 qualification means this part meets the automotive reliability stress and temperature requirements for use in under-hood and chassis-domain applications where the ambient can reach 175°C junction temperature. The OEM auditor will ask for the PPAP documentation — Taiwan Semiconductor provides it with this grade. ## What the key ratings mean for your BOM The 15.3V reverse standoff voltage (working voltage) sets the DC bias where the diode's leakage is negligible — a 12V battery rail with 3.3V of headroom before the breakdown knee at 17.1V minimum. The 25.5V clamping voltage ensures the protected circuit sees no more than that across the TVS during a surge. Peak pulse current of 60A at the 10/1000µs waveform tells you the surge-handling capability: a 1500W part at 25.5V clamp delivers that current. The wide -55°C to 175°C operating range covers cold-crank and hot-soak conditions without derating concerns.","metaTitle":"1.5KE18CAHB0G TVS Diode, 1500W, Bidirectional, DO-201","metaDescription":"1.5KE18CAHB0G TVS diode from Taiwan Semiconductor, AEC-Q101 qualified, 1500W peak pulse, 15.3V standoff, bidirectional, DO-201.","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":"Bulk","Applications":"-","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":"1.5KE18","Operating Temperature":"-55°C ~ 175°C (TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Voltage - Breakdown (Min)":"17.1V","Voltage - Clamping (Max) @ Ipp":"25.5V","Voltage - Reverse Standoff (Typ)":"15.3V","Current - Peak Pulse (10/1000µs)":"60A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5369","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a688563676897fea683fa9d5a5542f4e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What compliance documentation does Taiwan Semiconductor provide for this TVS?","answer":"As an AEC-Q101 qualified part, the manufacturer provides PPAP documentation, RoHS compliance, and REACH declarations.
