The automotive grade (AEC-Q100 qualified) extends the operating temperature range to -40°C to 125°C, which covers under-hood and chassis-domain environments where commercial-grade parts would derate or fail. ## Package and mounting The 3750 Vrms isolation rating is the 1-minute withstand voltage per UL 1577. For a 48 V or 400 V bus system, that gives a solid margin for reinforced insulation in a single device. The 75 kV/µs common-mode transient immunity is the spec that matters when this isolator sits between a controller and a SiC or GaN gate driver — those switching edges dump several kV/µs across the isolation barrier, and a part with lower CMTI will latch or corrupt data. At 75 kV/µs minimum, the ADUM140E1WBRWZ handles the fast edges from modern wide-bandgap stages without extra filtering. Propagation delay is 13 ns max in both directions, with pulse-width distortion held to 3 ns max. That keeps the data eye open for 150 Mbps NRZ signaling — the 2.5 ns rise/fall times are fast enough that the signal-integrity budget goes to the PCB trace, not the isolator. ## 4/0 input configuration — all channels on one side The channel direction is fixed: all four inputs on Side 1, all outputs on Side 2. That is a deliberate choice for applications like SPI isolation (SCLK, MOSI, MISO, CS) where data flows from the controller to the peripheral on three lines and back on one — but here you get only forward-direction channels. If your design needs bidirectional or mixed-direction isolation, the ADUM142D0BRWZ (2/2 split) is the same package and isolation rating with two channels in each direction. It is ROHS3 compliant.","metaTitle":"ADUM140E1WBRWZ Digital Isolator, 150Mbps, 3750Vrms","metaDescription":"ADI ADUM140E1WBRWZ general-purpose digital isolator: 4-channel, 150Mbps, 3750Vrms isolation, automotive grade, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"General Purpose","Grade":"Automotive","Package":"Tube","Data Rate":"150Mbps","Technology":"Magnetic Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"No","Package / Case":"16-SOIC (0.295\\\", 7.50mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"1.8V ~ 5.5V","Number of Channels":"4","Voltage - Isolation":"3750Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"4/0","Rise / Fall Time (Typ)":"2.5ns, 2.5ns","Supplier Device Package":"16-SOIC","Pulse Width Distortion (Max)":"3ns","Propagation Delay tpLH / tpHL (Max)":"13ns, 13ns","Common Mode Transient Immunity (Min)":"75kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.68","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.68000","currency":"USD"},{"qty":10,"price":"$4.20700","currency":"USD"},{"qty":25,"price":"$3.97680","currency":"USD"},{"qty":100,"price":"$3.44660","currency":"USD"},{"qty":250,"price":"$3.26988","currency":"USD"},{"qty":500,"price":"$2.93404","currency":"USD"},{"qty":1000,"price":"$2.47450","currency":"USD"},{"qty":2500,"price":"$2.35078","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADuM140D_140E_141D_141E_142D_142E.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does ADUM140E1WBRWZ require isolated power?","answer":"No — the ADUM140E1WBRWZ does not include an integrated isolated DC-DC converter.
