ADUM131D1BRZ

Overview

The ADUM131D1BRZ is a triple-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features a 2:1 channel configuration (two forward, one reverse) within a 16-pin SOIC package. Key electrical parameters include a data rate of 150 Mb/s, isolation voltage of 3000 Vrms, and common-mode transient immunity of 75 kV/µs. The device operates on a supply voltage range of 1.8 V to 5 V with a typical current consumption of 8.8 mA. Propagation delay is 7.2 ns, with rise/fall times of 2.5 ns. It supports SPI protocols and functions within an operating temperature range of -40°C to +125°C.

Feature Summary

• Integrates three independent digital isolation channels using proprietary iCoupler magnetic coupling technology for robust signal transmission.
• Provides high common-mode transient immunity to maintain signal integrity in electrically noisy environments.
• Supports unidirectional data flow with a flexible 2:1 channel configuration suitable for complex interface requirements.

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing galvanic isolation for safety compliance
• Power electronics control circuits demanding high-speed signal transfer

Procurement Notes

Verify the specific suffix '1BRZ' to confirm the 16-pin SOIC tube packaging and lead-free RoHS compliance status. Ensure the procurement source provides valid traceability documentation for Analog Devices components. Confirm that the required quantity matches the tube packaging format rather than reel or cut tape options. Check for any regional distribution restrictions or limited availability notices before finalizing orders.

Selection Notes

Select this component when a triple-channel isolator with 3000 Vrms isolation is required. It is suitable for applications needing 150 Mbps data rates and 75 kV/µs CMTI. Consider the 16-pin SOIC footprint for PCB layout constraints. Compare against the ADUM231 series if higher 5000 Vrms isolation voltage is necessary instead of the standard 3000 Vrms provided here.

Part Context

This part belongs to the ADuM131D family of general-purpose digital isolators. It shares the core iCoupler architecture with other members like the ADUM130D but offers a distinct 3-channel configuration. The '1BRZ' designation specifies the commercial grade temperature range, SOIC-16 package, and tube shipping method, distinguishing it from reel-packaged or industrial-grade variants.

Replacement Considerations

The ADUM231D1BRIZ-RL serves as a functional substitute offering identical channel count and speed but with increased 5000 Vrms isolation voltage. Verify pin compatibility and thermal performance when swapping between the 3000 Vrms ADUM131D1BRZ and the 5000 Vrms ADUM231D1BRIZ-RL variant.
