ADUM230D0BRWZ

Overview

The ADUM230D0BRWZ is a triple-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides 5000 Vrms isolation with a common-mode transient immunity of 75 kV/µs. The device supports data rates up to 150 Mbps and operates within a supply voltage range of 1.7 V to 5.5 V. It features unidirectional signal transmission in a 3:0 channel configuration. The component is housed in a 16-lead SOIC package with increased creepage distance and functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Utilizes iCoupler magnetic coupling technology for robust signal isolation without optical components.
• Provides high common-mode transient immunity of 75 kV/µs to maintain signal integrity in noisy environments.
• Features a 16-lead SOIC package designed with increased creepage distance for enhanced safety compliance.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced insulation barriers
• Power metering applications with high-voltage separation requirements

Procurement Notes

Verify the specific suffix (WZ) against the manufacturer's current datasheet to confirm package dimensions and tape-and-reel specifications. Ensure compatibility with RoHS 3 standards if required by your region. Cross-reference the part number with official Analog Devices distributors to confirm availability status and lead times, as manufacturing notifications may affect production schedules.

Selection Notes

Select this component when a triple-channel unidirectional isolator is required with 5000 Vrms basic isolation. It is suitable for designs needing 150 Mbps data throughput and operation up to 125°C. Consider the 16-SOIC footprint for PCB layout constraints. Verify that the 3:0 input-to-output channel ratio matches the system architecture needs.

Part Context

This part belongs to the ADuM230 series of robust digital isolators. It shares the iCoupler technology foundation with other devices in the family but is distinct in its triple-channel configuration and specific package variant. The series is designed for general-purpose isolation where high reliability and low power consumption are critical.

Replacement Considerations

Check for ADUM230E1BRIZ or ADUM230D0BRIZ variants for potential pin-compatible alternatives with different packaging or minor electrical parameter variations. Confirm that any substitute maintains the same 5000 Vrms isolation rating and 150 Mbps data rate capability.
