LT4356IDE-3#TRM

Overview

The LT4356IDE-3#TRM is a board-mount surge stopper manufactured by Analog Devices Inc. designed to protect loads from high voltage transients. It operates within a wide input voltage range of 4 VDC to 80 VDC and features a shutdown current of 7 µA. The device utilizes an SOIC-16 surface mount package with SMD/SMT termination. It supports an operating temperature range from -40°C to +125°C and includes fault latchoff functionality.

Feature Summary

• Stops high voltage surges by regulating output during overvoltage events through external N-channel MOSFET control
• Provides reverse input protection down to -60V and withstands shutdown pin voltages up to 100V
• Integrates adjustable latchoff fault timer and auxiliary amplifier for level detection

Applications

• Automotive and avionics surge protection
• Hot swap and live insertion systems
• High side switch for battery powered systems

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or official manufacturer channels. Confirm the specific suffix indicates tape and reel packaging. Ensure compliance with RoHS standards and check for recent product change notifications affecting specifications or manufacturing location before finalizing procurement orders.

Selection Notes

Select this variant for applications requiring extended industrial temperature ranges and surface mount integration. The IDE-3 designation specifies the DFN-12 package configuration combined with the -3 series electrical characteristics. Evaluate the need for fault latchoff behavior versus non-latching modes when designing circuit protection strategies for sensitive downstream electronics.
