LT4356HDE-3#TRPBF

Overview

The LT4356HDE-3#TRPBF is a board mount surge stopper manufactured by Analog Devices Inc., designed for robust circuit protection in demanding environments. It operates within a voltage range of 4 VDC to 80 VDC and features a quiescent current rating of 40 uA. The component supports an extended industrial temperature range from -40°C to +125°C, ensuring reliability in automotive, avionics, and industrial applications. It utilizes a DFN-12 surface-mount package with dimensions of 4 mm length, 3 mm width, and 0.75 mm height. The device includes fault latchoff functionality to secure the system during abnormal conditions.

Feature Summary

• Integrated fault latchoff mechanism that maintains protection state after surge events
• Wide input voltage capability supporting 4 VDC to 80 VDC operation
• Extended temperature range suitable for harsh automotive and industrial environments

Applications

• Automotive electronic systems requiring high-reliability surge protection
• Avionics power distribution networks needing robust overvoltage defense
• Industrial control equipment operating in extreme temperature conditions

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing components. Confirm the manufacturer part number matches exactly to ensure correct fault latchoff configuration. Check RoHS compliance documentation for regulatory adherence. Validate the DFN-12 footprint compatibility with your PCB design before procurement. Ensure availability status aligns with project timelines as supply may be limited.

Selection Notes

Select this variant when extended temperature performance down to -40°C is required compared to commercial grade options. Choose the DFN-12 package for compact board space constraints while maintaining thermal stability. Opt for the #TRPBF suffix if automated surface-mount assembly processes are utilized. Consider the 40 uA quiescent current for low-power standby requirements. Verify that the 80 VDC maximum rating exceeds the system's peak surge expectations.

Part Context

This component belongs to the LT4356-3 series of surge stoppers from Analog Devices. The series provides integrated solutions for protecting sensitive electronics from transient voltage spikes. The H-grade designation indicates the extended industrial temperature range variant. The DE suffix specifies the DFN-12 package type used for this specific part number.

Replacement Considerations

LT4356CDE-3#PBF offers similar functionality but in a commercial temperature range (0°C to +70°C). LT4356HMS-3#PBF provides the same electrical characteristics but in an MSOP-10 package. LT4356CS-3#PBF is available in an SOIC-16 package for different footprint requirements.
