LT4356HS-2#PBF

Overview

The LT4356HS-2#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 quiescent current rating of 250 uA. The device is housed in a SOIC-16 surface-mount package with dimensions of 10 mm length, 3.99 mm width, and 1.75 mm height, weighing 379 mg. It supports PCB mounting and functions reliably across an extended temperature range from -40°C to +125°C. This component belongs to the LT4356-1 series and is classified under surge suppressors.

Feature Summary

• Provides integrated board-level surge protection for sensitive electronic circuits
• Operates effectively across wide industrial and automotive temperature extremes
• Utilizes surface-mount technology for compact PCB integration

Applications

• Automotive systems requiring high-temperature reliability
• Avionics equipment demanding robust power line protection
• Industrial control applications exposed to harsh electrical environments

Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm RoHS compliance status and check for specific shipping restrictions applicable to your region. Ensure the SOIC-16 package matches your PCB footprint requirements before ordering. Review datasheet specifications for thermal management needs given the 125°C maximum operating temperature.

Selection Notes

Select this variant when high-temperature operation up to 125°C is required compared to lower temperature grades. The 250 uA quiescent current specification should be evaluated against system power budget constraints. Ensure the 4V to 80V input range aligns with the target application's supply voltage. Consider the SOIC-16 package size relative to available board space.

Part Context

This component is part of the LT4356-1 series of surge stoppers from Analog Devices. It serves as a specialized protection device for power distribution lines, distinct from general-purpose regulators or logic ICs. The HS suffix indicates the high-temperature grade variant within this product family.

Replacement Considerations

LT4356IS-2#PBF offers similar functionality but with a lower maximum operating temperature of 85°C and reduced quiescent current of 100 uA. LT4356HDE-2#PBF provides equivalent performance in a different package configuration. Verify pinout compatibility and thermal characteristics when substituting.
