LT4363HS-2#PBF

Overview

The LT4363HS-2#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 a SOIC-16 surface-mount package. The device supports a maximum operating temperature of +125°C and a minimum of -40°C. It includes automatic retry functionality after fault conditions, distinguishing it from latch-off variants. The component is designed for board mounting in harsh environments.

Feature Summary

• Provides high-voltage surge protection with integrated current limiting capabilities
• Features automatic retry mechanism following cool-down delays after fault events
• Includes overvoltage detection that inhibits retry if voltage exceeds specific thresholds

Applications

• Automotive electronic systems requiring robust power input protection
• Avionics equipment needing reliable surge suppression in critical circuits
• Industrial control systems exposed to transient voltage spikes

Procurement Notes

Verify the exact suffix designation when ordering, as variations such as TRPBF indicate tape-and-reel packaging while PBF denotes tube packaging. Confirm availability status directly with authorized distributors, as supply constraints may affect lead times. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment.

Selection Notes

Select this model when automatic recovery from fault conditions is required rather than manual reset. Compare against LT4363HS-1#PBF if latching behavior upon fault is preferred instead of auto-retry. Consider the SOIC-16 package dimensions and thermal characteristics during PCB layout planning to ensure adequate heat dissipation under sustained load conditions.

Part Context

This component belongs to the LT4363 series of high-voltage surge stoppers. It serves as a protective interface between power sources and sensitive downstream circuitry. The device integrates MOSFET drive logic and protection algorithms to manage input transients effectively.

Replacement Considerations

LT4363HS-2#TRPBF offers identical electrical performance but utilizes tape-and-reel packaging suitable for automated assembly processes.
