LT4356HMS-3

Overview

The LT4356HMS-3#PBF is a board mount surge stopper manufactured by Analog Devices Inc., designed for robust power line protection. It operates within a voltage range of 4 VDC to 80 VDC and features a low quiescent current rating of 40 uA. The component utilizes an MSOP-10 surface-mount package with dimensions of 3 mm in length, 3 mm in width, and 0.86 mm in height. It supports PCB mounting and functions reliably across an extended temperature range from -40 C to +125 C.

Feature Summary

• Integrates fault latchoff capability to secure the load during surge events
• Provides high accuracy overvoltage and overcurrent protection
• Designed for automotive, avionics, and industrial applications

Applications

• Automotive systems
• Avionics equipment
• Industrial control units

Procurement Notes

Verify the complete part number including suffixes such as #PBF against official Analog Devices documentation to ensure correct packaging and compliance specifications. Confirm availability status through authorized distributors, as supply levels may vary. Cross-reference the datasheet for specific handling and storage requirements prior to integration into final assemblies.

Selection Notes

Select this component when board-level surge protection with fault latching is required for 4V to 80V DC lines. The MSOP-10 package suits space-constrained designs needing wide operating temperatures. Ensure the application environment aligns with the specified -40 C to +125 C range and that the 40 uA quiescent current fits system power budgets.

Part Context

This device belongs to the LT4356 series of Surge Stoppers, which are specialized integrated circuits for protecting sensitive electronics from transient voltage spikes and reverse polarity conditions. The series offers various package options and temperature grades to accommodate diverse design constraints across multiple sectors.

Replacement Considerations

Compatible substitutes include other variants within the LT4356 family such as LT4356CS-3#PBF or LT4356IS-3#PBF, provided the package type and temperature range meet the design requirements. Verify pinout compatibility and electrical parameters before substitution.
