LT4363HMS-2#TRPBF

Overview

The LT4363HMS-2#TRPBF is a high-voltage surge stopper manufactured by Analog Devices Inc., designed for board-level protection. It operates within an input supply range of 4 VDC to 80 VDC and features a current rating of 1.2 mA. The component utilizes an MSOP-12 surface-mount package with dimensions of 4.04 mm x 3.00 mm and a height of 1.10 mm. It supports an extended industrial temperature range from -40°C to +85°C. This device automatically retries after overvoltage or overcurrent conditions, providing robust protection for sensitive downstream circuitry in demanding environments.

Feature Summary

• Automatically retries operation after cool down delay following sustained overvoltage or overcurrent events
• Integrates current limiting to protect the external MOSFET against output overloads
• Provides high-voltage surge suppression with clamping capabilities up to 80V DC input

Applications

• Automotive electronics systems
• Avionics power distribution networks
• Industrial control equipment

Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when sourcing components. Confirm that the HMS variant meets the required industrial temperature specifications for your application environment. Ensure compatibility with the target PCB footprint for the MSOP-12 package during procurement planning.

Selection Notes

Select this model when automatic recovery from fault conditions is required rather than latching shutdown. Consider the MSOP-12 package size constraints and the 4V to 80V operating window. Evaluate if the 1.2mA current limit aligns with the load requirements and thermal dissipation capabilities of the system design.

Part Context

This part belongs to the LT4363 series of high-voltage surge stoppers with current limit. It is functionally related to variants like LT4363HS-2#PBF but differs in package type and manufacturing lot specifications. The series provides integrated protection solutions for protecting low-voltage loads from high-voltage transients on power buses.

Replacement Considerations

LT4363HMS-2#PBF serves as the tube-packaged equivalent of this reel version.
