ADUM1301WSRWZ35

Overview

The ADUM1301WSRWZ35 is a triple-channel digital isolator utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 2.7V to 5.5V and supports data rates up to 1Mbps. The device provides 2500Vrms isolation voltage with a minimum common-mode transient immunity of 25kV/µs. Propagation delay is typically 100ns, and it functions across an operating temperature range of -40°C to +125°C. Packaged in a 16-SOIC surface-mount format, it features two transmitters and one receiver configuration.

Feature Summary

• Implements iCoupler magnetic coupling technology for signal transmission without optical components
• Provides robust galvanic isolation between circuit domains
• Supports high-speed digital communication channels
• Designed for automotive reliability standards

Applications

• Automotive electronic control units requiring isolated communication

Procurement Notes

Verify the specific suffix '35' against official Analog Devices documentation to confirm package type and moisture sensitivity level. Ensure compatibility with existing PCB footprints for the 16-SOIC variant. Cross-reference RoHS compliance status with current regulatory requirements before finalizing procurement decisions.

Selection Notes

Select this component when three isolated bidirectional or unidirectional channels are required within a compact footprint. Consider the 1Mbps data rate limit and 100ns propagation delay for timing-sensitive applications. Evaluate the 2500Vrms isolation rating against system safety requirements and verify thermal performance within the specified industrial temperature range.

Part Context

This part belongs to the ADuM1300/ADuM1301 series of triple-channel digital isolators from Analog Devices. These devices integrate iCoupler technology to replace traditional optocouplers, offering improved performance and reliability. The series is widely used in applications demanding high isolation voltage and low power consumption.

Replacement Considerations

Official parameter-equivalent substitutes include ADUM1301ARWZ and ADUM1301ARWZ-RL. Verify pinout compatibility and electrical specifications before substitution. Check manufacturer notices for any design changes affecting form, fit, or function.
