LT4356HS-2#TRPBF

Overview

The LT4356HS-2#TRPBF is a board mount surge protector manufactured by Analog Devices Inc., designed for high-voltage applications ranging from 4 VDC to 80 VDC. It operates within a temperature range of -40°C to +125°C and utilizes an SOIC-16 surface-mount package with SMD/SMT termination. The component features a maximum quiescent current of 250 uA and is intended for use in automotive, avionics, and industrial environments.

Feature Summary

• Provides robust protection against voltage surges on printed circuit boards
• Integrates fault latchoff functionality for enhanced system safety
• Supports wide input voltage ranges up to 80 VDC

Applications

• Automotive electronic systems
• Avionics power distribution
• Industrial control equipment

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm that the manufacturer officially supports this reel configuration for the LT4356HS-2 variant. Ensure compatibility with automated pick-and-place assembly processes if volume production is planned. Cross-reference the datasheet for any recent product change notifications affecting the reel specifications.

Selection Notes

Select this component for designs requiring integrated surge suppression with fault latching capabilities. The SOIC-16 package offers a balance between thermal performance and board space efficiency. Consider the 250 uA quiescent current impact on overall system power budget. Validate that the 80 VDC maximum rating aligns with the peak transient voltages present in the target application environment.

Part Context

This part belongs to the LT4356 series of Surge Stopper ICs from Analog Devices. The series includes variants with different packages and latchoff configurations. The HS-2 designation specifically denotes the SOIC-16 package version with fault latchoff functionality, distinguishing it from other series members like the MSOP or DFN options.

Replacement Considerations

LT4356HS-2#PBF is a verified tube-packaged substitute for the same electrical function.
