LT4363HMS-1#TRPBF

Overview

The LT4363HMS-1#TRPBF is a high-voltage surge stopper with current limit, manufactured by Analog Devices Inc. It operates within an input supply range of 4 VDC to 80 VDC and features a typical quiescent current of 700 μA. The device utilizes a 12-pin MSOP package with dimensions of 4 mm length, 3 mm width, and 0.86 mm height. It supports a minimum operating temperature of -40°C and a maximum of +125°C. The component provides board-mount protection against transients up to 250V, limiting output to approximately 16.3V in standard configurations.

Feature Summary

• Integrates high-voltage surge suppression with internal current limiting capabilities for robust circuit protection.
• Features automatic retry functionality after fault conditions cool down, ensuring system recovery without manual intervention.
• Includes a shutdown pin that allows latching off the device during sustained overvoltage or overcurrent events.

Applications

• Automotive electronics systems requiring transient voltage protection
• Avionics power distribution networks
• Industrial equipment input stages

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing this component. Confirm availability status as restricted supply may apply. Ensure the ordering part number matches the exact MSOP-12 variant required for your PCB footprint. Cross-reference the datasheet revision to confirm pinout compatibility before finalizing procurement orders.

Selection Notes

Select this model for applications requiring high input voltage tolerance up to 80VDC. Consider the MSOP-12 package size constraints for space-limited designs. Evaluate the need for automatic retry versus latching shutdown based on system safety requirements. Verify thermal performance within the specified -40°C to +125°C operating range for your environment.

Part Context

This component belongs to the LT4363 series of high-voltage surge stoppers. It is designed to protect sensitive downstream electronics from input line disturbances. The device integrates a N-channel MOSFET driver and control logic to manage surge events efficiently while maintaining low standby power consumption.
