LT4363CS-2#TRPBF

Overview

The LT4363CS-2#TRPBF is a high voltage surge stopper with current limit manufactured by Analog Devices Inc. It operates within an input supply range of 4V to 80V DC and withstands transients up to 250V. The device features a maximum operating temperature of 125°C and utilizes a 16-pin SOIC package. It provides board-level protection against overvoltage and overcurrent conditions, incorporating a timer delay for fault response.

Feature Summary

• Integrates MOSFET protection against output overloads through built-in current limiting mechanisms.
• Automatically retries operation after sustained overvoltage or overcurrent conditions following a cool-down delay period.
• Limits high-voltage input transients to safe output levels while protecting downstream circuitry.

Applications

• Automotive systems requiring robust power input protection
• Avionics equipment needing reliable surge suppression
• Industrial control boards susceptible to voltage spikes

Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when sourcing from distributors. Confirm that the CS-2 variant aligns with automatic retry requirements rather than latch-off functionality. Ensure compatibility with the 16-pin SOIC footprint during procurement planning.

Selection Notes

Select this component for applications demanding high voltage tolerance up to 80V and transient survival up to 250V. The automatic retry feature distinguishes it from latch-off variants, making it suitable for systems requiring self-recovery after fault clearance without manual intervention.

Part Context

This part belongs to the LT4363 series of high voltage surge stoppers designed for board-level protection. It serves as a critical interface between potentially unstable power sources and sensitive electronic loads, ensuring system integrity during electrical disturbances.

Replacement Considerations

LT4363IS-2#PBF offers identical functionality in a tube package. LT4363HS-2#PBF provides extended temperature range capabilities. Verify pinout and thermal performance before substituting.
