LTC4366CDDB-2#TRMPBF

Surge Suppression ICS Overview

The LTC4366CDDB-2#TRMPBF is a high voltage surge stopper manufactured by Analog Devices Inc., designed for board mount applications. It operates within a voltage range of 4.5 V to 12 V and features a maximum supply current of 15 uA. The device is housed in an 8-WFDFN package with dimensions of 3x2 mm, utilizing surface mount technology (SMD/SMT). It supports industrial, automotive, and avionic surge protection environments, functioning reliably across an operating temperature range from -55°C to +125°C. The component is supplied in cut tape or reel packaging formats.

Surge Suppression ICS Feature Summary

• Utilizes a floating topology architecture to manage high voltage transients without internal voltage limitations
• Controls external N-channel MOSFETs to regulate output voltage during overvoltage events
• Features adjustable output clamping thresholds via external resistor networks
• Includes built-in thermal shutdown mechanisms to protect the load during fault conditions

Surge Suppression ICS Applications

• Industrial control system power distribution protection
• Automotive electronic module surge suppression
• Avionic equipment high-voltage transient protection

Surge Suppression ICS Procurement Notes

Verify availability status directly with authorized distributors as supply constraints may apply. Confirm that the specific suffix matches the required temperature grade and retry functionality. Ensure compatibility with the intended PCB footprint and external MOSFET selection. Review the latest datasheet revision for any design changes or updated recommended operating conditions prior to final procurement decisions.

Surge Suppression ICS Selection Notes

Select this variant when industrial-grade temperature performance (-55°C to +125°C) is required alongside automatic retry capabilities after fault clearance. Compare against the LTC4366CDDB-1#TRMPBF if manual reset functionality is preferred over automatic recovery. Consider the LTC4366CTS8-1#TRMPBF for lower voltage applications requiring SOT-23-8 packaging instead of DFN. Validate external component ratings against the maximum expected surge voltages in the target application environment.

Surge Suppression ICS Part Context

This component belongs to the LTC4366 series of high voltage surge stoppers, which are engineered to protect sensitive downstream electronics from severe voltage spikes. The series employs a unique floating architecture that allows it to operate above the protected rail, distinguishing it from traditional clamp-based solutions. This family is widely utilized in harsh environments where reliability against load dump and inductive switching transients is critical for system integrity.
