LT4363CMS-1#TRPBF

Overview

The LT4363CMS-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 quiescent current of 1.2 mA. The device utilizes an MSOP-12 surface-mount package with dimensions of 4 mm in length, 3 mm in width, and 0.86 mm in height. It supports SMD/SMT termination types and functions reliably across a temperature range from -55°C to +125°C. This component is designed for board mount applications requiring robust protection against electrical surges.

Feature Summary

• Integrates high-efficiency switching technology to manage high voltage inputs while minimizing power loss during normal operation.
• Provides active current limiting to protect downstream MOSFETs and loads from output overloads and short circuits.
• Features automatic retry functionality that restores power after transient faults clear, enhancing system availability.

Applications

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

Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging configuration when sourcing. Confirm the MSOP-12 footprint matches the target PCB layout requirements. Ensure the operating temperature range meets the environmental specifications of the final assembly. Cross-reference the datasheet for any recent design changes or pinout updates before integration.

Selection Notes

Select this component for applications requiring protection between 4 VDC and 80 VDC inputs. The wide industrial temperature range suits harsh environments. Consider the MSOP-12 package size for space-constrained designs. Evaluate the need for automatic retry versus latching shutdown based on system recovery protocols.

Part Context

This part belongs to the LT4363 series of high voltage surge stoppers. It shares functional similarities with other variants like the LT4363CDE-1#PBF but differs in package type and thermal characteristics. The series is designed for protecting sensitive electronics from input voltage transients and reverse polarity events.

Replacement Considerations

LT4363MS-1#PBF offers identical functionality in a standard tube package instead of tape-and-reel. LT4363MPMS-1#PBF provides the same performance in a larger MSOP-12 package with enhanced thermal dissipation capabilities for high-power applications.
