ADUM3402TRWZ-EP-RL

Overview

The ADUM3402TRWZ-EP-RL is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 3.135V to 5.5V and supports data rates up to 10Mbps. The device features bidirectional channels in a 16-SOIC package with an insulation voltage of 2500Vrms and a common-mode transient immunity of 25kV/µs. It is qualified under AEC-Q100 standards for automotive applications and functions reliably across an extended temperature range of -55°C to 125°C.

Feature Summary

• Enhanced system-level ESD reliability for robust signal integrity
• AEC-Q100 qualification ensuring suitability for automotive environments
• Bidirectional channel configuration supporting flexible circuit design

Applications

• Automotive electronic control units requiring high isolation
• Industrial communication interfaces demanding noise immunity
• Medical equipment needing patient isolation safety

Procurement Notes

Verify the specific EP (Enhanced Product) suffix against current manufacturer availability lists, as these components often have restricted distribution or limited stock status. Confirm that the AEC-Q100 qualification meets your specific automotive grade requirements. Ensure the SOIC-16 footprint matches your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when high-speed bidirectional isolation is required alongside strict automotive reliability standards. Compare its 10Mbps rate against lower-speed alternatives if bandwidth is not critical. Consider the extended temperature range (-55°C to 125°C) for harsh environment deployments where standard industrial grades may fail.

Part Context

This part belongs to the ADuM340x family of quad-channel digital isolators. It shares architectural similarities with the ADUM3402 series but includes enhanced product specifications and automotive qualification. The TRWZ-EP-RL designation indicates tape-and-reel packaging with specific process controls for enhanced reliability.

Replacement Considerations

The ADUM3402BRWZ is a related commercial-grade variant within the same family. Verify if the reduced temperature range and lack of AEC-Q100 qualification are acceptable for your application before substituting.
