It provides 5000Vrms galvanic isolation across four unidirectional channels — two from Side 1 to Side 2, two from Side 2 to Side 1 — using magnetic coupling technology. The 5000Vrms isolation voltage rating qualifies this part for reinforced insulation in medical (IEC 60601) and industrial (IEC 61010) applications where a single-fault condition must not create a safety hazard. The 25kV/µs common-mode transient immunity means the output logic state holds steady when a fast high-voltage transient — like the switching edge in a motor-drive inverter or a lightning surge on a field cable — slams the isolation barrier. In practice, this CMTI number keeps the data link from bit-flipping in noisy environments where a lower-rated isolator would glitch. ## 25Mbps data rate and propagation delay — sizing the timing budget The 25Mbps data rate supports SPI clocks up to 12.5 MHz (half-duplex), UART at standard baud rates, and general-purpose GPIO isolation. The maximum propagation delay of 60ns in either direction and pulse-width distortion of 6ns are tight enough that a 25Mbps NRZ signal retains adequate eye opening across the barrier. If your bus runs faster than 25Mbps — say, a 50 MHz SPI — this part will not close timing; step up to a higher-rate isolator family. ## Package and footprint — 16-SOIC wide-body The wide-body gives the creepage distance needed to sustain the 5000Vrms rating — standard SOIC-16 narrow (3.90 mm) would not pass. The Tape & Reel suffix (-RL) means it ships on 13-inch reels, typical for volume production. If your application requires 125°C ambient (under-hood automotive, downhole tools), the ADUM5402WCRWZ-1RL carries an automotive-grade variant with the same 25Mbps data rate but lower 2500Vrms isolation.","metaTitle":"ADUM6402CRWZ-RL Digital Isolator, 5000Vrms, 25Mbps, 4-Ch","metaDescription":"ADUM6402CRWZ-RL quad-channel digital isolator with integrated IsoPower isolated DC-DC converter. 5000Vrms isolation, 25Mbps data rate, -40°C to 105°C.","metaKeywords":null},"attributes":{"series":"IsoPower®, iCoupler®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Type":"General Purpose","Series":"IsoPower®, iCoupler®","Package":"Tape & Reel (TR); Cut Tape (CT)","Data Rate":"25Mbps","Technology":"Magnetic Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"Yes","Package / Case":"16-SOIC (0.295\\\", 7.50mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Number of Channels":"4","Voltage - Isolation":"5000Vrms","Operating Temperature":"-40°C ~ 105°C","Inputs - Side 1/Side 2":"2/2","Rise / Fall Time (Typ)":"2.5ns, 2.5ns","Supplier Device Package":"16-SOIC","Pulse Width Distortion (Max)":"6ns","Propagation Delay tpLH / tpHL (Max)":"60ns, 60ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$17.18","priceTiers":[{"qty":1,"price":"$17.18000","currency":"USD"},{"qty":10,"price":"$15.78900","currency":"USD"},{"qty":25,"price":"$15.13480","currency":"USD"},{"qty":100,"price":"$13.33500","currency":"USD"},{"qty":250,"price":"$12.68056","currency":"USD"},{"qty":500,"price":"$11.86244","currency":"USD"},{"qty":1000,"price":"$10.88073","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/64cbf3e9142c9771c928705455ac2af4.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/ADUM6402CRWZ-RL/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between ADUM6402CRWZ-RL and ADUM6400CRWZ?","answer":"Both are quad-channel IsoPower isolators with 5000Vrms isolation and 25Mbps data rate.
