18014015401H

Overview

The Würth Elektronik 18014015401H is a four-channel digital isolator from the WPME-CDIS series, utilizing capacitive isolation technology. It operates within a supply voltage range of 2.375 V to 5.5 V and supports data rates up to 150 Mb/s. The device features a propagation delay of 12 ns with rise and fall times of 4 ns each. It provides an insulation voltage of 5000 Vrms and functions reliably across a temperature range of -40 °C to +125 °C. Packaged in a 16-pin SOIC (WSOIC) format, it offers high common-mode transient immunity.

Feature Summary

• Provides robust capacitive isolation between primary and secondary circuit sides
• Supports high-speed data transmission with 150 Mb/s rate capability
• Features default high output logic state for reliable signal initialization

Applications

• Industrial communication bus isolation
• Medical equipment signal isolation
• Power electronics gate drive isolation

Procurement Notes

Verify the specific suffix H indicates the default high output configuration as documented. Confirm the SOIC-16WB package dimensions match your PCB footprint requirements. Ensure thermal management strategies account for the maximum operating temperature of 125 °C during system integration.

Selection Notes

Select this component when high-speed digital isolation is required with a defined default high state. Compare against other WPME-CDIS variants if different channel counts or output polarities are needed. Validate that the 5000 Vrms insulation rating meets the safety standards of the target application environment.

Part Context

This part belongs to the WPME-CDIS family of capacitive digital isolators from Würth Elektronik. These devices are designed to replace traditional optocouplers in applications requiring higher speed and better reliability. The series emphasizes compact packaging and low power consumption for modern electronic systems.

Replacement Considerations

Check for direct pin-compatible alternatives within the same WPME-CDIS series that may offer different channel configurations or output states. Verify electrical parameters such as propagation delay and CMTI against existing design constraints before substitution.
