LT4356IDE-3#TRPBF

Overview

The LT4356IDE-3#TRPBF is a board-mount surge protector manufactured by Analog Devices Inc. It utilizes an external switch technology to manage overvoltage and surge events. The device operates within a voltage range of 4V to 80V DC and features a clamping voltage of 27V, which is adjustable. It is housed in a 12-WFDFN package with dimensions of 4mm x 3mm and a height of 0.75mm. The component supports surface mount installation and includes fault latchoff functionality for enhanced circuit protection.

Feature Summary

• Surge stopper with fault latchoff capability
• Utilizes external switch technology for overvoltage protection
• Adjustable clamping voltage at 27V

Applications

• Automotive systems
• Avionics equipment
• Industrial applications

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc., formerly Linear Technology. Ensure the part number matches the exact surge stopper specifications. Check for RoHS compliance documentation if required for your assembly process. Validate the DFN-12 package dimensions against your PCB footprint requirements before ordering.

Selection Notes

Select this component when adjustable clamping voltage is required for surge suppression. The external switch architecture allows flexibility in handling high-voltage transients up to 80V. Consider the 12-DFN package size for space-constrained designs. Verify that the application environment falls within the specified operating temperature range. Ensure the fault latchoff feature aligns with the system's recovery strategy after a surge event.

Part Context

This part belongs to the LT4356 series of surge suppressors from Analog Devices. The series includes variants like LT4356-1 and LT4356-2, which share similar protective functions but may differ in specific electrical characteristics or pin configurations. The LT4356 series is designed for robust board-level protection against transient voltage spikes in sensitive electronic circuits.

Replacement Considerations

LT4356CDE-3#TRPBF is a confirmed substitute part number within the same series. LT4356IDE-3#PBF is another variant offering the same core functionality in a tube package instead of tape and reel. Verify pin compatibility and electrical parameters before swapping.
