It features a unique ceramic/polymer composite barrier providing excellent isolation and virtually unlimited barrier life, utilizing symmetric magnetic coupling. The device supports data rates up to 110Mbps with a typical rise time of 4ns. It operates within a temperature range of -40°C to +125°C and offers an isolation voltage of 2500 Vrms. The component is designed for surface mount installation in compact packages.

Feature Summary

• Utilizes a unique ceramic/polymer composite barrier for excellent isolation performance
• Provides virtually unlimited barrier life through symmetric magnetic coupling technology
• Supports high-speed data transmission with low propagation delay characteristics

Applications

• Industrial automation systems requiring reliable signal isolation
• Medical equipment needing high-voltage isolation barriers
• Power electronics interfaces for gate drive isolation

Procurement Notes

Verify the specific suffix (e.g., -3B) against official NVE documentation to confirm package type and tape/reel specifications. Ensure the source document explicitly lists IL710-3B as a distinct part number variant rather than a generic family designation. Cross-reference tools may list parametrically similar parts but do not guarantee functional equivalence. Confirm compliance certifications such as VDE or UL if required for your application safety standards.

Selection Notes

Select this component when a single-channel isolation solution with high speed and long-term reliability is required. The ceramic/polymer barrier offers advantages over traditional oxide barriers regarding longevity. Consider the 110Mbps data rate and 4ns rise time for timing-sensitive applications. Ensure the operating temperature range meets the environmental requirements of the target system.

Part Context

The IL710 series represents NVE's high-speed digital isolators leveraging proprietary magnetic coupling technology. This series includes various channel configurations and package options. The IL710-3B specifically denotes a single-channel variant within this lineup, designed to replace optocouplers in many applications while offering superior performance metrics and reliability.

Replacement Considerations

Official substitutes include other variants within the IL710 series such as IL710-1E or IL710-3E, depending on package and configuration needs. Cross-reference tools can identify parametrically similar parts from other manufacturers, but functional equivalence must be verified against the original datasheet specifications.
