LT4356HDE-2#PBF

Overview

The LT4356HDE-2#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 40 uA. The component utilizes an SMD/SMT termination type housed in a DFN-12 package with dimensions of 4 mm length, 3 mm width, and 0.75 mm height. It supports an operating temperature range from -40 C to +125 C and is supplied in tube packaging.

Feature Summary

• Provides board-level protection against input voltage surges
• Integrates high-side switch control for power path management
• Features low quiescent current consumption for efficiency

Applications

• Automotive systems
• Avionics equipment
• Industrial applications

Procurement Notes

Verify the specific suffix #PBF indicates lead-free tape and reel or tube packaging status as per the manufacturer's latest documentation. Confirm that the DFN-12 footprint matches your PCB design requirements. Check for any Product Change Notifications (PCN) related to this part number to ensure compliance with current manufacturing standards before finalizing procurement plans.

Selection Notes

Select this component when designing circuits requiring robust surge protection for inputs between 4 VDC and 80 VDC. The wide operating temperature range of -40 C to +125 C makes it suitable for harsh environments. Consider the DFN-12 package size for space-constrained designs. Ensure the application does not require fault latch-off functionality, which is available in other variants like the LT4356HDE-3.

Part Context

This device belongs to the LT4356 series of Surge Stoppers designed by Analog Devices. It serves as a critical protection element in power distribution networks, safeguarding downstream components from transient overvoltage events. The HDE variant specifically denotes the DFN-12 package option within the broader family of surge suppression solutions.

Replacement Considerations

LT4356HDE-1#PBF offers similar protection without fault latch-off but may have different electrical characteristics. LT4356HDE-3#PBF includes fault latch-off functionality. LT4356HS-2#PBF provides the same function in an SOIC-16 package. Verify pinout compatibility and thermal performance when substituting.
