18014115401H

Overview

The Würth Elektronik 18014115401H is a WPME-CDIS series digital isolator featuring four independent channels in a 3/1 configuration. It provides 5000 Vrms isolation voltage and supports data rates up to 150 Mbps with a typical propagation delay of 12 ns. The device operates on a supply voltage range of 2.375 V to 5.5 V and includes high common-mode transient immunity of 150 kV/µs. Packaged in a 16-pin SOIC (SOIC-16WB) surface-mount format, it functions within an operating temperature range of -40°C to +125°C.

Feature Summary

• Provides galvanic isolation for four signal channels with a 3-input to 1-output configuration
• Ensures signal integrity through high common-mode transient immunity capabilities
• Supports high-speed data transmission with low propagation delay characteristics
• Operates reliably across extended industrial temperature ranges

Applications

• Industrial automation control systems requiring isolated communication interfaces
• Medical equipment needing safe patient isolation barriers
• Power electronics monitoring circuits demanding high-voltage separation
• Automotive electronic control units utilizing CAN or LIN bus isolation

Procurement Notes

Verify the specific suffix H against official Wurth Elektronik documentation to confirm pinout orientation and output logic state. Ensure compatibility with PCB footprint dimensions for the SOIC-16WB package. Confirm insulation ratings meet system safety standards before integration. Check moisture sensitivity levels for proper storage and reflow soldering profiles.

Selection Notes

Select this component when four-channel isolation is required within a compact surface-mount form factor. The 3/1 configuration suits applications where multiple inputs must be combined or monitored from one side. Consider the 150 Mbps speed limit for bandwidth requirements. Evaluate the 5000 Vrms rating against peak transient voltages in the target circuit environment.
