It uses magnetic coupling to transfer data across a 3750 Vrms isolation barrier at rates up to 40 Mbps. The six channels are arranged as 4 on side 1 and 2 on side 2, which maps directly to the four standard SPI signals (SCK, MOSI, MISO, chip select) plus two extra control lines — useful for daisy-chain enables or interrupt signals. The 40 Mbps data rate supports SPI clock frequencies up to 20 MHz in double-data-rate mode or 40 MHz single-edge — enough for most ADCs, DACs, and sensor interfaces. Propagation delay is 14 ns max (both directions), which keeps setup-and-hold margins comfortable at those clock rates. Pulse-width distortion is held to 2 ns max, so the duty cycle stays clean through the barrier. Common-mode transient immunity of 25 kV/µs minimum means the part won't glitch when a motor-drive IGBT switches or a relay coil kicks — critical in inverter and industrial environments. ## Package and footprint notes Housed in a 20-pin SSOP (0.209\" body width, 5.30 mm), surface-mount only. The 1.27 mm pitch is standard for SSOP and routes easily on two-layer boards. No isolated power output on this variant — you supply Vdd on both sides separately. ## Lifecycle and sourcing reality ROHS3 compliant. If you need a higher-isolation variant, the ADUM4150ARIZ-RL offers 5000 Vrms in the same 6-channel SPI configuration, though propagation delay increases to 24 ns.","metaTitle":"ADUM3150BRSZ SPI Digital Isolator, 40 Mbps, 3750 Vrms","metaDescription":"ADUM3150BRSZ SPI digital isolator from ADI. 6-channel unidirectional, 40 Mbps data rate, 3750 Vrms isolation, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":"iCoupler®, SPIsolator™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"SPI","Series":"iCoupler®, SPIsolator™","Package":"Tube","Data Rate":"40Mbps","Technology":"Magnetic Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"No","Package / Case":"20-SSOP (0.209\\\", 5.30mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Number of Channels":"6","Voltage - Isolation":"3750Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"4/2","Rise / Fall Time (Typ)":"2.5ns, 2.5ns","Supplier Device Package":"20-SSOP","Pulse Width Distortion (Max)":"2ns","Propagation Delay tpLH / tpHL (Max)":"14ns, 14ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.69","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$9.69000","currency":"USD"},{"qty":10,"price":"$8.75100","currency":"USD"},{"qty":25,"price":"$8.34400","currency":"USD"},{"qty":100,"price":"$7.24510","currency":"USD"},{"qty":250,"price":"$6.91952","currency":"USD"},{"qty":500,"price":"$6.30896","currency":"USD"},{"qty":1000,"price":"$5.49490","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADuM3150.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADUM3150BRSZ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/ADUM3150BRSZ when reusing this data.
