LT4356IS-1#PBF

Overview

The LT4356IS-1#PBF is a board mount surge stopper 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 is housed in a SOIC-16 surface-mount package with dimensions of 10 mm length, 3.99 mm width, and 1.75 mm height. Designed for industrial, automotive, and avionics applications, it supports an operating temperature range from 0°C to +70°C.

Feature Summary

• Provides integrated on-board surge protection for sensitive electronic circuits
• Operates with ultra-low static current consumption to minimize power loss
• Supports wide input voltage ranges suitable for various system architectures

Applications

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

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and tube packaging when sourcing. Confirm the IS-1 variant matches the required commercial temperature range of 0°C to +70°C against your design specifications. Ensure the SOIC-16 footprint aligns with your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when low standby current is critical for system efficiency. The SOIC-16 package offers a balance between thermal performance and board space. Consider the LT4356CS-1#PBF if a wider commercial temperature range is acceptable, or the LT4356HS-1#PBF for extended industrial temperature capabilities while maintaining similar electrical characteristics.

Part Context

This device belongs to the LT4356-1 series of surge suppressors designed to protect downstream components from transient voltage events. It integrates high-voltage switches and control logic to isolate loads during fault conditions. The series provides a compact solution for overvoltage protection without requiring external discrete components, simplifying design complexity.

Replacement Considerations

LT4356CS-1#PBF offers identical electrical performance but differs in temperature rating. LT4356HS-1#PBF provides extended industrial temperature operation. Verify pinout compatibility and package dimensions when substituting these variants to ensure seamless integration into existing designs.
