LT4363HS-2#TRPBF

Overview

The LT4363HS-2#TRPBF is a high-voltage surge stopper manufactured by Analog Devices Inc., designed for robust power distribution protection. It operates within an input voltage range of 4 VDC to 80 VDC and features a current rating of 1.2 mA. 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 functions reliably across an operating temperature range from -40°C to +125°C. This component integrates current limiting and overvoltage protection mechanisms to safeguard downstream circuitry from transient events.

Feature Summary

• Integrates high-voltage surge stopping capability with built-in current limiting to protect against output overloads.
• Features automatic retry functionality after cool-down delays following sustained overvoltage or overcurrent conditions.
• Provides precise output regulation during overvoltage events, clamping the output voltage to safe levels.

Applications

• Automotive electronic systems requiring high-voltage transient protection
• Avionics power distribution networks needing reliable surge suppression
• Industrial control equipment exposed to harsh electrical environments

Procurement Notes

Verify the specific suffix designation when ordering, as it indicates the tape-and-reel packaging format distinct from tube-packaged variants. Confirm that the SOIC-16 footprint matches your PCB layout requirements. Ensure the 4 VDC to 80 VDC input range aligns with your system's operational voltage profile. Check for any recent product change notifications regarding manufacturing updates. Validate compliance with RoHS standards if required for your specific application regulations.

Selection Notes

Select this component when designing circuits that require protection against high-voltage transients up to 80 VDC. Consider the automatic retry feature if system recovery without manual intervention is necessary. Evaluate the thermal performance within the -40°C to +125°C range for your environmental conditions. Compare the 1.2 mA current rating against your load requirements to ensure adequate protection margins. Assess the SOIC-16 package dimensions for space constraints on the printed circuit board.

Part Context

This part belongs to the LT4363 series of high-voltage surge stoppers, which are engineered to protect sensitive electronics from damaging voltage spikes. The HS-2 variant specifically denotes the high-speed version with automatic retry capabilities, distinguishing it from latch-off models. These devices are critical in applications where power line integrity must be maintained despite external electrical disturbances or internal fault conditions.

Replacement Considerations

LT4363HS-2#PBF offers identical electrical characteristics but comes in tube packaging instead of tape-and-reel. LT4363IDE-2#PBF provides similar functionality in a different package style. Verify pinout compatibility and thermal requirements before substituting with other Surge Stopper family members.
