LTC4366MPDDB-2#TRMPBF

Surge Suppression ICS Overview

The LTC4366MPDDB-2#TRMPBF is a high-voltage surge stopper manufactured by Analog Devices Inc., designed for board-mount protection applications. It operates within a voltage range of 4.5 V to 12 V and features a quiescent current rating of 15 µA. The component is housed in an 8-DFN package with surface-mount termination. It supports industrial, automotive, and avionic surge protection environments, functioning effectively across a temperature range from -55 °C to +125 °C.

Surge Suppression ICS Feature Summary

• Utilizes a floating topology architecture that allows the device to operate above the protected rail voltage without requiring internal circuitry rated for the full input voltage.
• Controls an external N-channel MOSFET to regulate output voltage during overvoltage transients, clamping the load voltage to a user-defined threshold via external resistors.
• Incorporates an auto-retry mechanism that automatically attempts to restore power after a fault condition clears, ensuring continuous operation in transient-heavy environments.

Surge Suppression ICS Applications

• Automotive electronics protection against load dump and other high-voltage transients on vehicle power lines
• Avionic systems requiring robust power distribution protection in harsh electromagnetic and thermal environments
• Industrial control systems protecting sensitive DC bus infrastructure from motor startup surges and switching noise

Surge Suppression ICS Procurement Notes

Verify availability status carefully as this specific part number may be subject to limited supply or factory special order constraints. Confirm RoHS compliance details and ensure the ordering suffix matches the required tape-and-reel packaging format. Cross-reference the manufacturer's latest datasheet revision to confirm pinout compatibility and electrical specifications before finalizing procurement orders.

Surge Suppression ICS Selection Notes

Select this variant when operating within the 4.5 V to 12 V input range and requiring automatic recovery from fault conditions. Ensure the external MOSFET selection supports the expected surge energy levels and voltage ratings. Verify that the thermal performance of the 8-DFN package meets the system's dissipation requirements under worst-case transient scenarios.

Surge Suppression ICS Part Context

This component belongs to the LTC4366 series of high-voltage surge stoppers, which are engineered to protect downstream circuitry from severe voltage spikes. The MPDDB designation indicates the military/industrial grade temperature range and specific packaging configuration. It serves as a critical interface between noisy power sources and sensitive electronic loads in high-reliability sectors.

Surge Suppression ICS Replacement Considerations

LTC4366MPDDB-1#TRMPBF: Identical package and thermal profile but lacks the auto-retry feature found in the -2 variant. LTC4366IDDB-2#TRMPBF: Industrial grade equivalent with similar functionality but potentially different temperature qualification ranges compared to the MPDDB specification.
