LT4356CMS-3#PBF

Overview

The LT4356CMS-3#PBF is a board mount surge stopper manufactured by Analog Devices Inc., designed for robust power line protection. It operates within a voltage range of 4 VDC to 80 VDC and features a low quiescent current rating of 30 uA. The component utilizes an MSOP-10 surface-mount package with SMD/SMT termination, measuring 3 mm in length, 3 mm in width, and 0.86 mm in height. It supports PCB mounting and functions reliably across an operating temperature range from 0°C to +70°C. This device belongs to the LT4356-3 series and serves as a specialized surge suppressor for critical electronic systems.

Feature Summary

• Integrates fault latchoff capability for enhanced system safety during surge events
• Provides high accuracy overvoltage and overcurrent protection boundaries
• Designed for low static current operation to minimize power consumption

Applications

• Automotive electronics systems
• Avionics equipment protection
• Industrial control circuitry

Procurement Notes

Verify the specific suffix #PBF indicates lead-free tape and reel packaging compliance. Confirm the MSOP-10 package dimensions match your PCB footprint requirements. Ensure the 0°C to +70°C commercial temperature grade aligns with your environmental specifications. Check for any recent Product Change Notifications regarding manufacturing updates or material substitutions before finalizing procurement orders.

Selection Notes

Select this component when integrating a compact surge stopper with fault latchoff functionality into space-constrained designs. The MSOP-10 package offers a balance between thermal performance and board area efficiency. Consider the 30 uA quiescent current for battery-sensitive applications. Verify that the 4 VDC to 80 VDC input range covers your system's nominal and transient voltage levels without requiring external biasing.

Part Context

This part belongs to the LT4356 family of ideal diode controllers and surge stoppers. The -3 suffix typically denotes variants with specific fault handling characteristics, such as latchoff modes, distinguishing it from non-latching versions like the -1 series. These devices are engineered to protect downstream components from reverse polarity, overvoltage, and surge conditions common in harsh electrical environments.

Replacement Considerations

LT4356CMS-1#TRPBF: Similar MSOP-10 package but lacks fault latchoff feature; suitable if automatic recovery is preferred. LT4356HMS-3#PBF: Extended temperature range (-40°C to +125°C) with higher quiescent current (40 uA); appropriate for automotive or industrial environments requiring wider thermal tolerance.
