18014215401H

Overview

The Würth Elektronik 18014215401H is a WPME-CDIS series digital isolator featuring four independent channels in a 16-SOIC package. It provides 5000 Vrms isolation voltage with a data rate of 150 Mbps and typical CMTI of 150 kV/µs. Operating on a supply voltage range of 2.375 V to 5.5 V, it exhibits a propagation delay of 12 ns and pulse width distortion of 13 ns. The device supports high-temperature operation from -40°C to +125°C.

Feature Summary

• Four-channel capacitive digital isolation architecture
• High common-mode transient immunity for noise rejection
• Wide operating temperature range for harsh environments
• Standard logic output configuration

Applications

• Industrial automation control systems
• Medical equipment signal isolation
• Automotive electronic modules
• Power supply feedback loops

Procurement Notes

Verify the specific suffix H against the manufacturer datasheet to confirm pinout and electrical characteristics match design requirements. Ensure ESD protection protocols are followed during handling due to sensitive CMOS input structures. Confirm RoHS compliance status via official documentation before integration into regulated assemblies.

Selection Notes

Select this component when four isolated channels are required within a compact surface-mount footprint. The 150 Mbps speed suits moderate-speed digital communication interfaces. Evaluate thermal management needs as the SOIC-16WB package dissipates heat differently than larger packages. Compare CMTI ratings against system noise levels to ensure reliable signal integrity under high dv/dt conditions.

Part Context

This part belongs to the WPME-CDIS family of capacitive digital isolators from Würth Elektronik. These devices utilize proprietary capacitive coupling technology to transmit signals across isolation barriers without magnetic components. The series offers various channel counts and output configurations to support diverse interface requirements in modern electronic designs.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching isolation voltage, data rate, and package dimensions with alternative manufacturers' catalogs.
