LT4356HDE-1#TRPBF

Overview

The LT4356HDE-1#TRPBF is a board mount surge stopper manufactured by Analog Devices Inc. It operates within a voltage range of 4 VDC to 80 VDC and features a DFN-12 package with SMD/SMT termination. The device has a quiescent current rating of 40 uA and functions across an extended temperature range from -40 C to +125 C. Designed for robust circuit protection, it utilizes a tube packaging format.

Feature Summary

• Provides integrated board-level surge protection against transient voltage events
• Operates efficiently with low quiescent current consumption
• Supports wide input voltage ranges up to 80 VDC

Applications

• Automotive systems requiring overvoltage protection
• Avionics equipment needing reliable surge suppression
• Industrial control circuits demanding high-temperature stability

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging configuration distinct from tube variants. Confirm the HDE grade meets the required -40 C to +125 C operating temperature specifications for your application environment. Ensure the DFN-12 footprint matches your PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component when extended industrial temperature performance is mandatory alongside high voltage tolerance. The DFN-12 package offers a compact solution compared to larger SOIC options. Consider the 40 uA current draw relative to power-sensitive designs. Validate that the surge stopper functionality aligns with system protection strategies rather than simple switching applications.

Part Context

This part belongs to the LT4356-1 series of surge suppressors designed for protecting sensitive electronics from voltage spikes. It complements other Analog Devices power management solutions by providing dedicated input protection. The series includes various package options like MSOP and DFN to suit different space constraints.
