LT4356HS-1#PBF

Overview

The LT4356HS-1#PBF is a board mount surge stopper manufactured by Analog Devices Inc., designed for robust circuit protection in demanding environments. It operates within a voltage range of 4 VDC to 80 VDC and features a maximum quiescent current of 40 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. It supports an extended operating temperature range from -40°C to +125°C, ensuring reliability in automotive, avionics, and industrial applications.

Feature Summary

• Integrated surge stopper functionality for board-level overvoltage protection
• Low static current consumption for efficient power management
• Extended industrial and automotive temperature rating capability

Applications

• Automotive electronic systems
• Avionics equipment
• Industrial control circuits

Procurement Notes

Verify the specific suffix and package type against the official datasheet to ensure compatibility with design requirements. Confirm RoHS compliance status through manufacturer documentation. Check for any recent Product Change Notifications (PCN) that may affect material composition or manufacturing location. Ensure the ordering quantity matches the tube packaging specifications provided in the official product data.

Selection Notes

Select this component when high-voltage surge protection is required for sensitive downstream electronics in harsh environments. The wide operating temperature range makes it suitable for automotive and industrial sectors where standard commercial grade parts may fail. Compare the 40 uA quiescent current against system power budgets to ensure efficiency meets design constraints.

Part Context

This part belongs to the LT4356-1 series of surge suppressors from Analog Devices. It is distinct from other variants like the CS or IS versions primarily by its extended temperature range (-40°C to +125°C). The HS suffix indicates the specific thermal and operational class within the broader LT4356 family, tailored for high-stress applications.

Replacement Considerations

LT4356IS-1#PBF offers similar functionality but with a lower operating temperature range (-40°C to +85°C). LT4356CS-1#PBF provides commercial grade performance with a limited temperature range (0°C to +70°C). Verify thermal requirements before substituting.
