18024015401L

Overview

The Würth Elektronik 18024015401L is a four-channel digital isolator featuring an integrated isolated DC/DC power module. It operates within a supply voltage range of 3.15 V to 5.5 V and supports data rates up to 100 Mbps. The device provides 5 kVrms insulation voltage with a typical propagation delay of 10 ns. It is housed in a SOIC-WB-16 package and functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Integrates an isolated DC/DC converter, requiring only a single external power supply for operation
• Provides high-speed signal isolation with a maximum data rate of 100 Mbps
• Features low default channel output status for safe initialization states

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced insulation barriers
• Power electronics control circuits with high common-mode transient immunity

Procurement Notes

Verify the specific suffix 'L' against the manufacturer's current datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure compatibility with the SOIC-WB-16 footprint during PCB layout. Confirm RoHS compliance status if required by your regional regulations before finalizing procurement orders.

Selection Notes

Select this component when a compact solution combining four isolated channels with an internal power source is needed. It eliminates the need for separate isolated DC/DC converters, reducing board space. Consider the 100 Mbps speed limit and 5 kV isolation rating to ensure they meet the system's noise immunity and safety standards.

Part Context

This part belongs to the WPME-CDIP series from Würth Elektronik, designed for robust digital signal transmission across isolation barriers. The series emphasizes integration by embedding the power conversion stage directly within the isolator package, simplifying system architecture compared to discrete solutions.
