18024115401H

Overview

The Würth Elektronik 18024115401H is a four-channel digital isolator featuring an integrated isolated DC/DC power converter. It operates within a supply voltage range of 3.15V to 5.5V and supports data rates up to 100 Mb/s. The device provides reinforced isolation with a rating of 5000 Vrms for 60 seconds. It exhibits a typical common-mode transient immunity of 150 kV/µs and a propagation delay of 10 ns. The component functions in unidirectional mode and is housed in a 16-SOIC wide body package, suitable for surface mount applications across temperatures from -40°C to 125°C.

Feature Summary

• Integrated isolated DC/DC power converter delivering 0.65W output
• Reinforced insulation barrier rated at 5000 Vrms
• High common-mode transient immunity of 150 kV/µs

Applications

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

Procurement Notes

Verify the specific suffix 'H' against the manufacturer's current datasheet to confirm pinout and electrical characteristics match project requirements. Ensure the 16-SOIC wide body footprint aligns with PCB layout constraints. Confirm that the integrated power converter specifications meet the load demands of the isolated side circuitry before finalizing procurement.

Selection Notes

Select this component when a self-contained isolated power source is required alongside data isolation to reduce external component count. The 100 Mb/s data rate suits standard industrial protocols. Consider the 56.2 mA operating current and thermal performance within the SOIC-16WB package when designing the thermal management strategy for high-density assemblies.

Part Context

This part belongs to the Würth Elektronik WPME-CDIP series of digital isolators. These devices are designed to facilitate rapid data transmission across isolation barriers while providing necessary power to the secondary side. The series integrates both isolation technology and power conversion into a single compact package, simplifying system design for applications demanding robust galvanic separation.

Replacement Considerations

Cross-reference with other Würth Elektronik parts in the same series for alternative channel configurations or package options. Verify compatibility with existing board layouts if substituting with similar isolators from different manufacturers, paying close attention to pin definitions and isolation ratings.
