Rated for a peak pulse current of 4.5A under the 10/1000µs condition, this part handles repetitive surge events in 12V and 24V automotive systems where the nominal bus voltage sits well below the 214V standoff — typical for load-dump and inductive kickback protection on ECU power inputs. ## AEC-Q101 qualification and temperature range The 175°C TJ max provides margin above the 150°C typical for automotive-grade passives. The series designation 'Automotive, AEC-Q101, 1.5KE' confirms it meets the stress test and reliability requirements for automotive electronic systems, including temperature cycling, ESD, and humidity bias.","metaTitle":"1.5KE250AHB0G TVS Diode, 1.5kW, 214V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE250AHB0G Zener TVS diode, 1500W peak pulse, 214V reverse standoff, AEC-Q101 automotive, 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","Series":"Automotive, AEC-Q101, 1.5KE","Package":"Bulk","Applications":"Automotive","Mounting Type":"Through Hole","Package / Case":"DO-201AA, DO-27, Axial","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE250","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"237V","Voltage - Clamping (Max) @ Ipp":"344V","Voltage - Reverse Standoff (Typ)":"214V","Current - Peak Pulse (10/1000µs)":"4.5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5564","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a688563676897fea683fa9d5a5542f4e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the 1.5KE250AHB0G suitable for automotive applications?","answer":"Yes, it is AEC-Q101 qualified and explicitly listed for automotive applications."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/taiwan-semiconductor-corporation/1.5KE250AHB0G","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/taiwan-semiconductor-corporation/1.5KE250AHB0G when reusing this data.
