That means it is qualified for automotive-grade stress and reliability screens — temperature cycling, high-temperature reverse bias, and ESD/latch-up per the AEC-Q101 discrete semiconductor qualification standard. The part provides a single bidirectional channel — it clamps both polarities of a transient, which is the typical configuration for protecting AC-coupled or floating signal lines. The reverse standoff voltage is 6.63V, meaning the TVS draws negligible leakage below that rail voltage. ## Package and replacement fit — DO-201AA axial The 1.5KE8.2CHE3/73 is housed in a DO-201AA (DO-27) axial-lead package with through-hole mounting. The supplier device package is designated 1.5KE. Any replacement candidate must match this footprint — the body diameter and lead spacing of the DO-201AA — and the 1500W peak pulse rating at the same 10/1000µs test condition. The part ships in Tape & Box (TB) packaging, which is the standard bulk format for axial diodes.","metaTitle":"1.5KE8.2CHE3/73 Vishay TransZorb TVS, 1500W, AEC-Q101","metaDescription":"Vishay 1.5KE8.2CHE3/73 automotive TVS diode, 1500W peak pulse, 6.63V standoff, AEC-Q101 qualified.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Vishay General Semiconductor - Diodes Division","Type":"Zener","Series":"Automotive, AEC-Q101, TransZorb®","Package":"Tape & Box (TB)","Applications":"Automotive","Mounting Type":"Through Hole","Package / Case":"DO-201AA, DO-27, Axial","Product Status":"Obsolete","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE8.2","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Voltage - Breakdown (Min)":"7.38V","Voltage - Clamping (Max) @ Ipp":"12.5V","Voltage - Reverse Standoff (Typ)":"6.63V","Current - Peak Pulse (10/1000µs)":"120A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cbd949ebcf4c95d5b4ea8fdecf87536f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to 1.5KE8.2CHE3/73?","answer":"Any replacement must match the DO-201AA axial package, the 1500W peak pulse rating at 10/1000µs, the 6.63V reverse standoff voltage, and the bidirectional configuration.
