LT4363IDE-2#TRPBF

Overview

The LT4363IDE-2#TRPBF is a high voltage surge stopper manufactured by Analog Devices Inc., designed for robust power input protection. It operates within an input supply range of 4 VDC to 80 VDC and withstands survival transients up to 250V. The device features current limiting to protect the MOSFET against output overloads, with automatic retry functionality after cool-down delays in sustained fault conditions. It is housed in a compact DFN-12 surface-mount package, suitable for applications requiring efficient board-level surge suppression.

Feature Summary

• Provides high-voltage surge protection with integrated current limiting capabilities
• Features automatic retry mechanism following cool-down delays after fault conditions
• Designed for efficient board-mount installation in space-constrained environments

Applications

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

Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm the specific suffix matches the required tape-and-reel packaging configuration. Ensure compliance with RoHS directives and check for any product change notifications that may affect pinout or electrical characteristics prior to final design integration.

Selection Notes

Select this variant for designs requiring automatic recovery from overcurrent or overvoltage events without manual intervention. The DFN-12 package offers a smaller footprint compared to SOIC options, making it ideal for dense PCB layouts. Consider thermal management requirements as the device manages significant transient energy during surge events.

Part Context

This component belongs to the LT4363 family of high-efficiency switching surge stoppers. The 'IDE' designation indicates a specific industrial temperature grade and DFN-12 package type, while the '#TRPBF' suffix specifies the tape-and-reel packaging format with lead-free finish. This distinguishes it from tube-packaged variants like the LT4363IDE-2#PBF.

Replacement Considerations

LT4363IDE-2#PBF (same function, different tube packaging). LT4363IMS-2#PBF (MSOP-12 package alternative). LT4363IS-2#PBF (SOIC-16 package alternative).
