LT4356HMS-1

Overview

The LT4356HMS-1 is a board mount surge protector manufactured by Analog Devices Inc. It operates within a voltage range of 4 VDC to 80 VDC and features an MSOP-10 surface-mount package with SMD/SMT termination. The component has a maximum quiescent current rating of 30 uA and functions as a surge stopper. It supports an operating temperature range from -40 C to +85 C.

Feature Summary

• Provides integrated overvoltage and overcurrent protection for sensitive downstream circuitry
• Utilizes low static current architecture to minimize power consumption during standby states
• Designed for high-reliability applications in automotive, avionics, and industrial environments

Applications

• Automotive electronic systems requiring robust surge suppression
• Avionics equipment demanding reliable power line protection
• Industrial control systems needing overvoltage safeguarding

Procurement Notes

Verify the specific suffix HMS against official Analog Devices documentation to confirm package type and temperature grade. Confirm RoHS compliance status through the manufacturer's latest datasheet or product change notifications. Check authorized distributor availability as supply may be restricted. Ensure the ordering part number matches the exact functional requirements before procurement.

Selection Notes

Select this component when designing circuits that require precise overvoltage and overcurrent protection with low quiescent current draw. The MSOP-10 package suits space-constrained PCB layouts. Verify that the 4 VDC to 80 VDC input range aligns with the system's nominal voltage levels. Consider the -40 C to +85 C operating range for environmental compatibility.

Part Context

The LT4356HMS-1 belongs to the LT4356 series of Surge Stopper devices from Analog Devices. This family provides integrated solutions for protecting power inputs from transient events. The device integrates internal MOSFETs and control logic to manage fault conditions automatically without external sensing components.

Replacement Considerations

LT4356IMS-1#PBF offers similar functionality in an MSOP-10 package but differs in operating temperature range (-40 C to +85 C). LT4356MPMS-1#TR provides extended temperature capability (-55 C to +125 C) in the same package. Verify pinout and electrical specifications before substitution.
