It integrates two bidirectional channels (Side 1/Side 2 input count 2/1) to handle the clock and data lines of an I²C link, supporting data rates up to 1Mbps — fast-mode plus capable. The 25kV/µs minimum common-mode transient immunity (CMTI) is the spec that matters in motor-drive or inverter-fed environments — fast switching edges on the high-voltage side won't couple through and corrupt the bus. ## Automotive qualification and temperature grade This part is intended for automotive ECU applications where the isolation barrier must survive the thermal cycling and vibration profile of a vehicle's powertrain or chassis domain. The ROHS3 compliance is standard for current production. ## Package and mounting — 8-SOIC Housed in an 8-SOIC package with 3.90mm body width, surface-mount only. The supplier device package is 8-SOIC. Standard SOIC-8 footprint; no exposed pad, so thermal dissipation is through the leads and board copper.","metaTitle":"ADUM1251WARZ-RL7 I²C Digital Isolator, 2500Vrms, 1Mbps","metaDescription":"ADUM1251WARZ-RL7 I²C digital isolator with magnetic coupling, 2500Vrms isolation, 1Mbps data rate, -40°C to 105°C, active production.","metaKeywords":null},"attributes":{"series":"Automotive","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"I²C","Series":"Automotive","Package":"Tape & Reel (TR); Cut Tape (CT)","Data Rate":"1Mbps","Technology":"Magnetic Coupling","Channel Type":"Bidirectional, Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"No","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Number of Channels":"2","Voltage - Isolation":"2500Vrms","Operating Temperature":"-40°C ~ 105°C","Inputs - Side 1/Side 2":"2/1","Rise / Fall Time (Typ)":"26ns, 52ns","Supplier Device Package":"8-SOIC","Pulse Width Distortion (Max)":"145ns, 85ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.1","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.16000","currency":"USD"},{"qty":1,"price":"$8.10000","currency":"USD"},{"qty":10,"price":"$7.31600","currency":"USD"},{"qty":25,"price":"$6.97520","currency":"USD"},{"qty":100,"price":"$6.05660","currency":"USD"},{"qty":250,"price":"$5.78440","currency":"USD"},{"qty":500,"price":"$5.27404","currency":"USD"},{"qty":1000,"price":"$4.81500","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADUM1250_1251.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is ADUM1251WARZ-RL7 automotive qualified?","answer":"Yes.
