LT4356IDE-3#PBF

Overview

The LT4356IDE-3#PBF 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 an external switch topology. The device is housed in a DFN-12 package with dimensions of 4 mm x 3 mm x 0.75 mm. It supports surface mount technology (SMD/SMT) and has a quiescent current rating of 40 uA. The component is designed for industrial, automotive, and avionics applications, operating between -40 C and +125 C.

Feature Summary

• Provides protection against high voltage transients using an external switch configuration
• Includes fault latchoff functionality to secure the load during abnormal conditions
• Offers adjustable clamping voltage capabilities for precise transient management

Applications

• Automotive electronic systems requiring robust overvoltage protection
• Avionics equipment needing reliable power line safeguarding
• Industrial control circuits susceptible to electrical noise and surges

Procurement Notes

Verify the specific suffix and package type when ordering to ensure compatibility with your design requirements. Confirm that the component meets all necessary environmental standards for your intended application environment. Check official manufacturer documentation for the most current availability status and handling instructions prior to procurement.

Selection Notes

Select this component when designing circuits that require active surge suppression with latching behavior. Ensure the external switch MOSFET selected can handle the maximum input voltage and current specifications. Consider the thermal performance of the DFN-12 package relative to the expected power dissipation in your specific layout.

Part Context

This part belongs to the LT4356 series of Surge Stoppers from Analog Devices. These devices are engineered to protect sensitive downstream loads from high-voltage transients on power lines. The series utilizes an external pass element to achieve low insertion loss while providing fast response times to overvoltage events.

Replacement Considerations

LT4356CDE-3#PBF offers similar functionality with a different temperature range (-40 C to +125 C vs 0 C to +70 C). LT4356HDE-3#PBF provides extended temperature operation up to +125 C. Verify pinout and electrical parameters before substituting.
