It delivers 150 Mbps data rate per channel with 2.5 ns typical rise/fall times and 13 ns max propagation delay, making it suitable for isolating high-speed serial interfaces like SPI, CAN FD, or UART without introducing bus-timing margin problems. The 3750 Vrms isolation rating covers reinforced insulation requirements in medical, industrial, and grid-tied applications, while the 75 kV/µs minimum common-mode transient immunity (CMTI) keeps data integrity intact in motor-drive and inverter environments where fast switching edges threaten to couple noise across the barrier. ## Supply range and logic compatibility That wide supply range simplifies BOM consolidation when bridging different voltage islands on a mixed-signal board. The unidirectional channel configuration — two inputs on side 1, one input on side 2 — fits the typical isolated SPI pattern: MISO, MOSI, and SCLK crossing the barrier in one direction, with a dedicated return channel for data from the peripheral.","metaTitle":"ADUM131E1BRWZ-RL iCoupler 3-Ch Digital Isolator, 150 Mbps","metaDescription":"ADUM131E1BRWZ-RL is a 3-channel unidirectional digital isolator from ADI's iCoupler series. 150 Mbps data rate, 3750 Vrms isolation, 75 kV/µs CMTI.","metaKeywords":null},"attributes":{"series":"iCoupler®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"General Purpose","Series":"iCoupler®","Package":"Tape & Reel (TR); Cut Tape (CT)","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":"1.7V ~ 5.5V","Number of Channels":"3","Voltage - Isolation":"3750Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"2/1","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":"$3.4","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.40000","currency":"USD"},{"qty":10,"price":"$3.05300","currency":"USD"},{"qty":25,"price":"$2.88600","currency":"USD"},{"qty":100,"price":"$2.50130","currency":"USD"},{"qty":250,"price":"$2.37300","currency":"USD"},{"qty":500,"price":"$2.12928","currency":"USD"},{"qty":1000,"price":"$1.79578","currency":"USD"},{"qty":2000,"price":"$1.70599","currency":"USD"},{"qty":5000,"price":"$1.64186","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADuM130D_130E_131D_131E.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is ADUM131E1BRWZ-RL compatible with 3.3V logic?","answer":"Yes."},{"question":"What is the difference between ADUM131E1BRWZ-RL and the ADUM131E1BRWZ (non-tape)?","answer":"All electrical specs — 150 Mbps, 3750 Vrms, 75 kV/µs CMTI — are identical."},{"question":"How to use ADUM131E1BRWZ-RL for isolated SPI communication?","answer":"The 2/1 channel configuration maps directly to a three-wire SPI isolation: two channels on side 1 carry MOSI and SCLK to the peripheral, and the single channel on side 2 returns MISO.
