It provides 2500Vrms isolation between two power domains, with two channels on side 1 and two on side 2. The 2500Vrms isolation voltage is the basic working isolation rating — sufficient for reinforced insulation in many industrial and medical applications, but not the 5000Vrms tier found in the ADUM2402BRIZ. If your design requires 5kVrms isolation, the ADUM2402BRIZ is the pin-compatible upgrade, though it trades the -55°C low end for a -40°C to 105°C range. Common-mode transient immunity of 25kV/µs minimum ensures the isolator won't glitch when fast-switching edges (from IGBTs or SiC MOSFETs) couple across the isolation barrier. In motor drives or inverter stages, this rating directly determines whether the data link stays clean during PWM transitions. Propagation delay is 50ns max in either direction, with pulse-width distortion held to 3ns. That timing budget is tight enough for 10Mbps SPI or UART isolation without needing to re-time the bus. Rise and fall times of 2.5ns typical keep the signal edges sharp enough for the receiving side to clock cleanly. ## Supply voltage and logic compatibility The supply range spans 3.135V to 5.5V on both sides, so the part can run from a single 3.3V rail or mix 3.3V and 5V domains. This covers the common 5V logic isolation question — yes, it works with 5V logic on either side as long as the supply voltage matches. No isolated power output is provided; you need separate supplies for each side. ## Package and footprint notes Housed in a 16-pin SOIC with 7.50mm body width (the wide-body variant), the package provides 8 mm creepage distance typical for 2500Vrms reinforced isolation. The footprint is shared with other ADI quad-channel isolators, so a layout designed for the ADUM2402BRIZ (5kVrms) will accept this part without changes — useful for a single-board design that needs to scale isolation voltage across variants.","metaTitle":"ADUM3402TRWZ-EP iCoupler Digital Isolator, 2500Vrms, 10Mbps","metaDescription":"ADUM3402TRWZ-EP quad-channel digital isolator with 2500Vrms isolation, 10Mbps data rate, -55°C to 125°C range.","metaKeywords":null},"attributes":{"series":"iCoupler®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"General Purpose","Series":"iCoupler®","Package":"Tube","Data Rate":"10Mbps","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":"3.135V ~ 5.5V","Number of Channels":"4","Voltage - Isolation":"2500Vrms","Operating Temperature":"-55°C ~ 125°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)":"3ns","Propagation Delay tpLH / tpHL (Max)":"50ns, 50ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$18.73","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$18.73000","currency":"USD"},{"qty":10,"price":"$17.21200","currency":"USD"},{"qty":25,"price":"$16.49880","currency":"USD"},{"qty":100,"price":"$14.53680","currency":"USD"},{"qty":250,"price":"$13.82336","currency":"USD"},{"qty":500,"price":"$12.93154","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADuM3400-EP_3401-EP_3402-EP.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can ADUM3402TRWZ-EP be used for 5V isolation?","answer":"Yes.
