Breakdown occurs at 27V minimum (the avalanche threshold), and clamping is specified at 43.5V maximum when conducting 36A — the protected circuit must survive this clamping voltage for the pulse duration. The single bidirectional channel protects against both positive and negative transients in one device — useful for AC-coupled signal lines or power rails that see reverse surges. The -55°C to 175°C operating junction temperature range covers automotive under-hood ambient (125°C) with margin for self-heating during the surge pulse — the junction temperature rise during a single 10/1000µs pulse is typically under 25°C at rated power. Tape & Reel packaging supports automated insertion for through-hole assembly — the reel quantity is standard for the DO-201 form factor.","metaTitle":"1.5KE30CH TVS Diode, 1500W, 24.3V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE30CH bidirectional TVS diode, 1500W peak pulse power, 24.3V reverse standoff, 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":"1.5KE30","Operating Temperature":"-55°C ~ 175°C (TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Voltage - Breakdown (Min)":"27V","Voltage - Clamping (Max) @ Ipp":"43.5V","Voltage - Reverse Standoff (Typ)":"24.3V","Current - Peak Pulse (10/1000µs)":"36A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2712","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1a365530dc7ecf41756be3288a873e3f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is 1.5KE30CH's listed type and grade?","answer":"The 1.5KE30CH is a Zener-type bidirectional TVS diode with Automotive grade, qualified to AEC-Q101.
