LT4363HS-1#PBF

Overview

The LT4363HS-1#PBF is a board mount surge stopper manufactured by Analog Devices Inc. It operates within an input voltage range of 4 VDC to 80 VDC and features a minimum operating temperature of -40°C with a maximum of +125°C. The device utilizes an SOIC-16 surface-mount package with SMD/SMT termination, measuring 10 mm in length, 3.99 mm in width, and 1.75 mm in height. It includes current limiting capabilities and is designed for automotive, avionics, and industrial applications.

Feature Summary

• Provides high-voltage surge protection with integrated current limiting functionality
• Latches off following fault conditions requiring external reset via shutdown pin
• Supports operation across extended industrial and automotive temperature ranges

Applications

• Automotive systems
• Avionics equipment
• Industrial machinery

Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm RoHS compliance status and check for regional sales restrictions prior to ordering. Ensure the specific suffix matches design requirements as packaging variations may exist. Validate supply availability directly with the manufacturer due to potential limited stock situations.

Selection Notes

Select this variant when latch-off behavior is required after overvoltage or overcurrent events. The SOIC-16 package suits designs needing larger footprints compared to MSOP options. Verify that the 80VDC input rating aligns with system transient requirements. Consider thermal management needs given the 125°C maximum junction temperature limit.

Part Context

This component belongs to the LT4363 series of high-voltage surge stoppers. It shares functional similarities with other variants like the LT4363IDE-1#PBF but differs in package type and thermal characteristics. The series provides robust protection against input transients while maintaining low quiescent current consumption during normal operation.

Replacement Considerations

LT4363HS-2#PBF offers automatic retry instead of latch-off behavior.
