ADUM1301WTRWZ33-RL

Overview

The ADUM1301WTRWZ33-RL is a three-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 10 Mbps. The device features a common-mode transient immunity (CMTI) of 25 kV/µs and an isolation voltage rating of 2500 Vrms. Packaged in a 16-pin SOIC with a 7.50 mm width, it is automotive qualified under AEC-Q100 standards. The component functions bidirectionally with a propagation delay of 32 ns and operates across a temperature range of -40°C to +125°C.

Feature Summary

• Utilizes iCoupler magnetic coupling technology for galvanic isolation without external transformers.
• Automotive qualified under AEC-Q100 standards for reliability in vehicle applications.
• Provides high common-mode transient immunity of 25 kV/µs for noise-resistant signal transmission.
• Supports bidirectional data flow across three independent channels.

Applications

• Automotive motor control systems requiring isolated gate drive signals.
• Industrial inverters and converters needing robust signal isolation.
• Power supply circuits requiring feedback loop isolation.
• Medical equipment demanding high safety isolation standards.

Procurement Notes

Verify the specific suffix '33' against the official Analog Devices datasheet to confirm pinout or electrical parameter variations compared to standard variants. Ensure the ordering part number matches the required tape-and-reel packaging configuration. Cross-reference the AEC-Q100 qualification status with current manufacturer documentation to confirm active automotive compliance. Confirm the package width and lead form factor align with PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when bidirectional communication is required alongside unidirectional channels in a single package. The 10 Mbps data rate suits moderate-speed industrial interfaces. The wide operating temperature range and automotive qualification make it suitable for harsh environments. Compare power consumption figures against system budget constraints, as isolators draw quiescent current proportional to data activity. Ensure the 2500 Vrms isolation rating meets the specific safety clearance requirements of the target application.

Part Context

This part belongs to the ADUM1301 series of general-purpose digital isolators. It shares the same core architecture and package outline as other variants in the family but may differ in specific electrical characteristics or qualification levels due to the '33' suffix. The series is designed to replace bulky optical couplers in modern electronic designs, offering higher reliability and lower power consumption.

Replacement Considerations

Direct substitutes include ADUM1301ARWZ-RL and ADUM1301WTRWZ-RL. Verify if the '33' suffix denotes a specific binning or minor revision that requires exact matching. Check compatibility with existing PCB footprints and software configurations if the replacement affects timing parameters.
