LT4356CS-3#PBF

Overview

The LT4356CS-3#PBF 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 a maximum quiescent current of 30 uA. The component utilizes an SOIC-16 surface-mount package with dimensions of 10 mm length, 3.99 mm width, and 1.75 mm height. Designed for industrial applications, it functions reliably between 0°C and +70°C. This specific variant includes fault latchoff capability.

Feature Summary

• Surge stopper functionality with integrated fault latchoff mechanism
• Low static current consumption for power efficiency
• Surface-mount construction compatible with standard PCB assembly

Applications

• Automotive systems
• Avionics equipment
• Industrial control units

Procurement Notes

Verify the exact suffix against official Analog Devices documentation to confirm the presence of the fault latchoff feature, as this distinguishes the -3 variant from other series members. Confirm RoHS compliance status through the manufacturer's latest datasheet or product change notifications prior to finalizing procurement specifications.

Selection Notes

Select this component when protection against input surges is required alongside automatic shutdown upon fault detection. Ensure the operating environment remains within the specified commercial temperature range. Verify that the SOIC-16 footprint matches the target PCB design constraints before integration into the circuit architecture.

Part Context

This device belongs to the LT4356 family of ideal diode controllers and surge suppressors. The CS designation indicates a commercial temperature grade and SOIC-16 packaging. The -3 suffix specifically denotes the inclusion of a latchoff feature following a fault event, differentiating it from non-latching variants within the same product line.

Replacement Considerations

LT4356IS-3#PBF offers extended temperature range capabilities while maintaining similar functional characteristics.
