ADUM3201TRZ-EP

Overview

The ADUM3201TRZ-EP is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 25 Mb/s. The device provides an isolation voltage of 2500 Vrms with a common-mode transient immunity (CMTI) of 25 kV/µs. It features a propagation delay of 45 ns and unidirectional channel polarity. Packaged in an 8-lead SOIC, it functions across an operating temperature range of -40°C to +125°C.

Feature Summary

• Enhanced system-level ESD performance compliant with IEC 61000-4-x standards
• High-temperature operation capability extending to 125°C
• Robust magnetic coupling isolation for signal transmission

Applications

• Automotive electronic systems requiring AEC-Q100 qualified components
• Industrial communication interfaces demanding high CMTI
• Medical equipment needing enhanced safety isolation

Procurement Notes

Verify the specific suffix 'EP' indicates the enhanced product variant with extended temperature and ESD specifications. Confirm package type matches the 8-lead SOIC requirement. Check current availability status as distribution may be limited or subject to factory orders. Ensure compatibility with existing PCB footprints before integration.

Selection Notes

Select this component when high-temperature reliability and superior ESD protection are critical. The 25 Mb/s speed suits moderate-speed digital isolation needs. Compare against standard variants if automotive qualification or 125°C operation is not required. Verify power consumption fits the system budget at the target voltage.

Part Context

This part belongs to the ADUM3201 series of dual-channel digital isolators. It shares the core iCoupler architecture with other models but distinguishes itself through enhanced durability features. The EP designation typically signifies an extended product variant designed for harsh environments compared to standard commercial grades.
