LT4363IMS-1#TRPBF

Overview

The LT4363IMS-1#TRPBF is a high-voltage surge stopper manufactured by Analog Devices Inc., designed for board-mount protection. It operates within a voltage range of 4 VDC to 80 VDC and features a maximum quiescent current of 1.2 mA. The component utilizes an MSOP-12 surface-mount package with SMD/SMT termination. It supports an operating temperature range from -40°C to +85°C. This device integrates current limiting capabilities to protect downstream circuitry from input surges.

Feature Summary

• Provides high-voltage surge protection with integrated current limiting functionality
• Features latch-off behavior after fault detection to prevent damage
• Supports bidirectional circuit breaker operations in compatible configurations

Applications

• Automotive electronic systems requiring robust power line protection
• Avionics equipment needing reliable surge suppression
• Industrial control units exposed to transient voltage events

Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when sourcing. Confirm the IMS-1 variant matches the required thermal and electrical specifications for your design. Check official Analog Devices documentation for the latest lifecycle status, as availability may be restricted or subject to limited supply conditions depending on the region.

Selection Notes

Select this component when designing circuits that require protection against high-voltage transients up to 80 VDC. Ensure the application environment stays within the specified -40°C to +85°C operating range. Consider the MSOP-12 package size constraints during PCB layout. Verify that the latch-off feature aligns with the system's reset requirements following a surge event.

Part Context

This part belongs to the LT4363 series of high-efficiency switching surge stoppers. It is engineered to replace traditional fuses and diodes in high-voltage applications. The series offers improved efficiency and compact sizing compared to discrete solutions. It is widely used in critical infrastructure where power integrity is essential.

Replacement Considerations

LT4363IMS-1#PBF is the tube-packaged equivalent of this reel-part. LT4363MPMS-1#PBF serves as a military-grade alternative with extended temperature ranges. Verify pin compatibility and thermal performance before substituting.
