18024215401H

Overview

The Würth Elektronik 18024215401H is a four-channel digital isolator from the WPME-CDIP series, housed in a SOIC-WB-16 surface-mount package. It features an integrated isolated DC/DC converter module and operates with default high outputs. The device supports data rates up to 100 Mbps and provides 5000 Vrms isolation voltage. It functions within a supply voltage range of 3.15 V to 5.5 V, with a propagation delay of 10 ns. The component is rated for operation between -40°C and +125°C.

Feature Summary

• Integrates an isolated DC/DC converter module for single-supply operation
• Provides capacitive isolation technology with 5kVrms insulation voltage
• Features default high output logic state for all four channels

Applications

• Industrial communication interfaces requiring galvanic isolation
• Medical equipment signal transmission
• Automotive electronic control units

Procurement Notes

Verify the specific suffix 'H' against the manufacturer datasheet to confirm pinout and electrical characteristics match design requirements. Ensure the SOIC-WB-16 footprint aligns with PCB layout constraints. Confirm RoHS compliance status through official documentation before procurement.

Selection Notes

Select this component when a compact, four-channel isolator with integrated power conversion is required. The wide operating temperature range suits harsh environments. Verify that the 100 Mbps data rate meets system timing needs and that the 3.15 V minimum supply voltage is compatible with the target logic levels.

Part Context

This part belongs to the WPME-CDIP series of digital isolators by Würth Elektronik. These devices are designed to replace traditional optocouplers in applications demanding higher reliability and smaller form factors. The series emphasizes integrated power solutions to simplify circuit design.

Replacement Considerations

Check for direct substitutes within the same WPME-CDIP family or comparable four-channel isolators from other manufacturers. Ensure replacement parts maintain the 5kVrms isolation rating and SOIC-WB-16 package compatibility.
