ADUM1300WTRWZ35

Overview

The ADUM1300WTRWZ35 is a discontinued general-purpose digital isolator manufactured by Analog Devices Inc. It features three unidirectional channels with magnetic coupling technology, providing 2500Vrms isolation voltage. The device supports data rates up to 10Mbps and offers a common-mode transient immunity of 25kV/µs. Operating on a supply voltage range of 3V to 5.5V, it exhibits maximum propagation delays of 32ns for both low-to-high and high-to-low transitions. Packaged in a 16-SOIC surface-mount format, it is rated for automotive applications within an operating temperature range of -40°C to 125°C.

Feature Summary

• Utilizes iCoupler magnetic coupling technology for signal transmission without optical components
• Provides robust common-mode transient immunity suitable for noisy industrial environments
• Configured as a triple-channel unidirectional isolator for single-direction data flow
• Automotive-grade qualification ensures reliability under extended temperature conditions

Applications

• Motor control systems requiring galvanic isolation between controller and driver stages
• Industrial automation interfaces connecting PLCs to field devices
• Power supply feedback loops for isolated voltage sensing
• Inverter gate drive circuits in renewable energy systems

Procurement Notes

This component has been officially declared obsolete and is no longer in production. Verification of availability should focus exclusively on the listed parameter-equivalent substitutes provided by the manufacturer. Buyers must confirm that replacement parts match the original electrical specifications and package dimensions to ensure circuit compatibility. Direct sourcing from authorized distributors is recommended to avoid counterfeit products.

Selection Notes

Designers should evaluate the ADUM1300WTRWZ35's 10Mbps data rate against system timing requirements before considering alternatives. The 16-SOIC package width and pinout must be verified for PCB layout compatibility when selecting replacements. Since the part is end-of-life, engineers must prioritize substitutes that maintain the same 2500Vrms isolation rating and unidirectional channel configuration to preserve safety standards.

Part Context

The ADUM1300 series belongs to Analog Devices' iCoupler family of digital isolators, which replace traditional optocouplers using silicon transformer technology. This specific variant targets automotive and industrial markets requiring high reliability. The 'WTRWZ35' suffix denotes a specific tape-and-reel packaging configuration intended for automated assembly processes, distinguishing it from tube-packaged variants.
