LT4363MPMS-1#TRPBF

Overview

The LT4363MPMS-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 maximum operating current rating of 1.2 mA. The device is housed in a surface-mount MSOP-12 package, measuring 4 mm in length, 3 mm in width, and 0.86 mm in height. It supports an extended industrial temperature range from -55°C to +125°C. This component provides latch-off protection after a fault condition, requiring a shutdown signal reset.

Feature Summary

• Provides board mount surge protection for high voltage systems
• Integrates current limiting functionality to protect downstream components
• Features latch-off behavior upon sustained overvoltage or overcurrent faults

Applications

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

Procurement Notes

Verify the specific suffix designation against official documentation to confirm tape-and-reel packaging versus tube configuration. Ensure the selected variant matches the required latch-off reset mechanism and thermal specifications for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring robust protection against high voltage transients up to 80V. Consider the MSOP-12 footprint constraints and the need for external shutdown signaling to reset the latch-off state. Evaluate compatibility with automotive and avionics environmental standards during the design phase.

Part Context

This part belongs to the LT4363 series of high voltage surge stoppers. It is designed to replace traditional discrete protection schemes by integrating MOSFET drive and control logic into a single compact package. The series offers solutions for protecting sensitive electronics from input power anomalies.
