LT4356IS-3#TRPBF

Overview

The LT4356IS-3#TRPBF is a board-mount surge stopper manufactured by Analog Devices Inc. It provides overvoltage and overcurrent protection for sensitive electronics. The device features fault latchoff capability to isolate faults permanently until reset. It operates within a voltage range of 4 VDC to 80 VDC. The component is housed in a 16-pin SOIC package and utilizes surface mount technology (SMD/SMT) for PCB integration.

Feature Summary

• Integrates surge suppression with fault latchoff functionality
• Provides adjustable overvoltage and overcurrent protection boundaries
• Designed for board-mount applications requiring high accuracy

Applications

• Surge suppression in industrial systems
• Overvoltage protection for sensitive electronic circuits
• Overcurrent protection in distributed power architectures

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when reviewing distributor listings. Confirm the manufacturer is Analog Devices Inc. and not a generic supplier. Ensure the part number matches the exact LT4356IS-3 designation to avoid confusion with non-latch variants or different packages like MSOP. Cross-reference the datasheet version to ensure compatibility with current design requirements.

Selection Notes

Select this component when permanent fault isolation is required after a surge event. The adjustable nature allows customization of protection thresholds. Consider the 16-SOIC footprint for layout constraints. Evaluate the need for manual or automatic reset mechanisms associated with the latchoff feature. Compare against standard limiters if temporary protection suffices.

Part Context

This part belongs to the LT4356 family of Surge Stopper ICs from Analog Devices. It shares architectural similarities with other models in the series but differs in specific control interfaces and package options. The IS-3 variant specifically denotes the 16-SOIC package configuration with fault latchoff capabilities, distinguishing it from versions without latching or with different pinouts.

Replacement Considerations

LT4356IS-3#PBF serves as a tube-packaged alternative to the tape-and-reel LT4356IS-3#TRPBF. Both share identical electrical characteristics and functionality. Verify that the manufacturing source remains Analog Devices Inc. for both variants to ensure consistent performance specifications.
