I13TL1A0

Overview

The I13TL1A0 is a three-channel passive digital isolator designed for secondary referenced digital power system monitoring and control. It operates with an input voltage of 3.3V and provides 420V DC working voltage with 3000Vrms AC isolation. The device features a common mode transient immunity (CMTI) of 3kV/µs and utilizes an 8-LGA package type, specifically the LGA (10 x 10 mm) configuration. It supports T-Grade temperature range from -40°C to 125°C.

Feature Summary

• Passive design reduces system complexity while maintaining small footprint for high power density
• Enables secondary referenced digital power system monitoring and control when used with Vicor controllers
• Provides robust electrical isolation with 3000Vrms rating and 3kV/µs CMTI

Applications

• Secondary referenced digital power system monitoring
• Digital power system control interfaces
• High-density power conversion systems requiring galvanic isolation

Procurement Notes

Verify component authenticity through authorized Vicor distributors or direct manufacturer channels. Confirm package marking matches the 8-LGA specification. Ensure storage conditions comply with moisture sensitivity levels for LGA packages. Check for obsolescence status as digital isolators may have limited production lifecycles. Validate supply chain documentation against Vicor's official part number registry.

Selection Notes

Select this component when secondary referenced isolation is required for Vicor-based power architectures. The passive nature eliminates need for separate VCC supply on the isolated side. Consider thermal performance within the -40°C to 125°C operating range. Evaluate board space constraints given the 10x10mm LGA footprint. Ensure compatibility with D44TL1A0 digital controller for complete system integration.

Part Context

Part of Vicor's digital isolator family including MI13ML1A0 variant. Designed specifically for integration with Vicor's high-performance power modules and brick modules. Complements the D44TL1A0 digital monitor controller in complete power system solutions. Represents Vicor's approach to reducing system complexity through passive isolation technology.

Replacement Considerations

No publicly confirmed substitute part numbers are available. The I13TL1A0 is designed for specific integration with Vicor power architectures. Alternative generic digital isolators may not provide compatible interface characteristics or form factor. Consult Vicor engineering for potential migration paths if discontinuation occurs.
