LTC4364IMS-2#PBF

Overview

The LTC4364IMS-2#PBF is a board mount surge protector manufactured by Analog Devices Inc., designed for automotive, avionics, and industrial applications. It operates within a voltage range of 4 VDC to 80 VDC and features an MSOP-16 surface-mount package measuring 4 mm in length, 3 mm in width, and 0.86 mm in height. The device functions as a Surge Stopper with an ideal diode, utilizing external switching technology. It supports SMD/SMT termination types and is rated for operation between -40°C and +85°C.

Feature Summary

• Integrates ideal diode functionality to minimize power loss during normal operation
• Provides robust protection against input voltage surges and reverse polarity conditions
• Utilizes external switch control for customizable overvoltage threshold management

Applications

• Automotive electronic systems
• Avionics power distribution networks
• Industrial equipment power inputs

Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm the specific suffix matches project requirements, as variations may exist within the family. Review current supply status due to potential limited availability. Ensure compliance with RoHS directives and relevant environmental standards before integration into final assemblies.

Selection Notes

Select this variant when operating voltages fall between 4 VDC and 80 VDC and an MSOP-16 footprint is required. Consider the -40°C to +85°C temperature range against environmental constraints. Evaluate the need for integrated ideal diode behavior versus discrete solutions. Compare against other series members if higher temperature ratings or different package sizes are necessary for the specific design.

Part Context

This component belongs to the LTC4364 series of Surge Stoppers, which are specialized circuit protection ICs. These devices protect sensitive downstream electronics from transient voltage spikes and reverse polarity events common in harsh environments. The series offers configurable protection thresholds using external components, providing flexibility for various system architectures.

Replacement Considerations
