LT4363IMS-1#PBF

Overview

The LT4363IMS-1#PBF 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 an MSOP-12 surface mount package measuring 4 mm in length, 3 mm in width, and 0.86 mm in height. The device supports a maximum operating temperature of +125°C and a minimum of -55°C. It functions as a board mount surge protector designed for automotive, avionics, and industrial applications.

Feature Summary

• Provides integrated protection against high voltage surges and output overloads through internal current limiting mechanisms.
• Features latch-off behavior after fault conditions, requiring a specific shutdown signal sequence to reset the circuit.

Applications

• Automotive power systems
• Avionics equipment
• Industrial control circuits

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm that the MSOP-12 package matches design requirements. Ensure environmental specifications meet operational temperature ranges. Check datasheet revisions for any updates to electrical characteristics or pin configurations before finalizing procurement.

Selection Notes

Select this component when latch-off protection is required following a fault event. Compare against retry-based variants if automatic recovery is preferred. Verify that the 80V DC input rating aligns with system voltage levels. Consider thermal management capabilities within the specified temperature range during integration.

Part Context

This part belongs to the LT4363 series of high voltage surge stoppers. It shares functional similarities with other variants in the family but differs in fault response behavior. The IMS-1 suffix indicates specific package and performance characteristics distinct from other series members.
