It supports data rates up to 25Mbps across the isolation barrier, making it a fit for isolating SPI, UART, or general-purpose digital signals in industrial motor drives, medical equipment, and power-conversion systems where safety isolation is required. ## Package and mounting The 5000Vrms isolation rating is the headline spec for this part — it qualifies the device for reinforced insulation per IEC 60747-5-5, which is the threshold medical and industrial safety standards demand. The 25Mbps data rate comfortably handles isolated SPI clock lines at 20 MHz or two UART channels running at 1 Mbps each, with margin. Propagation delay is a maximum of 33.6 ns (tpHL), and pulse-width distortion stays under 4 ns — tight enough to avoid skew issues on a shared clock or data bus. Common-mode transient immunity is rated 50kV/µs (typical), which is the number to watch when the isolator sits between a microcontroller and a motor-drive power stage. Fast switching transients on the high-voltage side can couple through parasitic capacitance; a CMTI below 25 kV/µs would risk bit errors in that environment. This part's 50 kV/µs gives a solid margin for 600 V motor drives and SiC/GaN inverter stages. Supply voltage spans 1.71V to 5.5V on both sides, so it can bridge a 1.8V MCU domain to a 5V sensor interface without a level shifter. ## Package and rework considerations The 1.27 mm pitch leaves room for a standard iron tip or hot-air nozzle without bridging adjacent pins. The wide-body SOIC also provides the creepage distance needed to maintain the 5000Vrms rating across the board; keep the PCB slot under the isolator per the layout guidelines. ## Lifecycle and compliance No PCN or LTB schedule has been issued for this part as of the current date.","metaTitle":"MAX12931BAWE+ Digital Isolator, 5000Vrms, 25Mbps, 16-SOIC","metaDescription":"MAX12931BAWE+ general-purpose digital isolator: 5000Vrms isolation, 25Mbps data rate, 2 unidirectional channels, -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","Package":"Tube","Data Rate":"25Mbps","Technology":"Capacitive 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":"1.71V ~ 5.5V","Number of Channels":"2","Voltage - Isolation":"5000Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"1/1","Rise / Fall Time (Typ)":"1.6ns, 1.4ns (Max)","Supplier Device Package":"16-SOIC","Pulse Width Distortion (Max)":"4ns","Propagation Delay tpLH / tpHL (Max)":"32.5ns, 33.6ns","Common Mode Transient Immunity (Min)":"50kV/µs (Typ)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.6","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.60000","currency":"USD"},{"qty":10,"price":"$5.92600","currency":"USD"},{"qty":25,"price":"$5.60240","currency":"USD"},{"qty":100,"price":"$4.85550","currency":"USD"},{"qty":250,"price":"$4.60648","currency":"USD"},{"qty":500,"price":"$4.13340","currency":"USD"},{"qty":1000,"price":"$3.73500","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX12930-MAX12931.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does MAX12931BAWE+ have an equivalent from TI?","answer":"Texas Instruments offers the ISO7221C and ISO7221M, which are functionally similar dual-channel digital isolators with 25Mbps data rate and 5000Vrms isolation in a wide-body SOIC-16 package.
