18024015401H

Overview

The Würth Elektronik 18024015401H is a four-channel digital isolator featuring an integrated isolated DC/DC power module. It operates within a supply voltage range of 3.15V to 5.5V and supports data rates up to 100 Mbps. The device provides 5 kV isolation voltage with a typical common-mode transient immunity of 150 kV/µs. It utilizes a 16-pin SOIC package (7.50mm width) and functions across a temperature range of -40°C to 125°C. Key electrical parameters include a propagation delay of 20ns, rise time of 4ns, and maximum input current of 20µA.

Feature Summary

• Integrates an isolated DC/DC converter requiring only a single external power supply for both sides.
• Provides high common-mode transient immunity to prevent signal corruption in noisy environments.
• Maintains industrial standard pin configurations for direct compatibility with existing designs.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment signal transmission interfaces
• Power electronics control circuits

Procurement Notes

Verify the specific suffix 'H' against official Wurth documentation to confirm default output state and package variant. Ensure the selected component matches the required isolation voltage ratings for your safety standards. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement specifications.

Selection Notes

Select this component when a compact solution integrating power isolation is required to reduce external BOM count. The 100 Mbps speed suits moderate-speed digital communication protocols. Verify that the 16-SOIC footprint fits the PCB layout constraints and that the thermal performance meets the application's operating temperature requirements.

Part Context

This part belongs to the WPME-CDIP series of capacitive digital isolators from Würth Elektronik. These devices are designed to replace traditional optocouplers in applications demanding higher reliability and faster switching speeds. The series emphasizes compact form factors and robust isolation capabilities for modern electronic systems.

Replacement Considerations

Check for alternative parts within the same Würth series or comparable industry offerings that match the 16-SOIC footprint and 5kV isolation rating. Ensure any substitute maintains the integrated DC/DC feature if board space savings are critical.
