LT4356HDE-1#PBF

Overview

The LT4356HDE-1#PBF is a board mount surge stopper manufactured by Analog Devices Inc., designed for robust circuit protection. It operates within a voltage range of 4 VDC to 80 VDC and features a low quiescent current rating of 40 uA. The component is housed in a DFN-12 surface-mount package with dimensions of 4 mm in length, 3 mm in width, and 0.75 mm in height. It supports an extended industrial temperature range from -40°C to +125°C and utilizes SMD/SMT termination types for reliable PCB integration.

Feature Summary

• Provides integrated board-level surge suppression for sensitive electronics
• Features fault latchoff capability to isolate damaged circuits during severe events
• Operates with minimal static current consumption for power efficiency

Applications

• Automotive systems requiring high-temperature reliability
• Avionics equipment demanding strict surge protection standards
• Industrial control units operating in harsh environments

Procurement Notes

Verify availability status carefully as this part number may be subject to limited supply or factory special order constraints. Confirm the specific suffix matches the required thermal and electrical specifications for your design. Ensure compatibility with the DFN-12 footprint and check for any recent product change notifications that might affect pinout or material composition before finalizing procurement plans.

Selection Notes

Select this component when designing for automotive, avionics, or industrial applications requiring wide input voltage ranges up to 80 VDC. The H-grade variant ensures operation across a broad temperature spectrum suitable for demanding environments. Consider the DFN-12 package size for space-constrained layouts while ensuring adequate thermal management for the intended load conditions.

Part Context

This device belongs to the LT4356 series of surge suppressors, specifically the LT4356-1 family. It serves as a critical protection element against transient voltage spikes that could otherwise damage downstream components. The series is engineered to handle significant energy surges while maintaining system integrity during normal operation.

Replacement Considerations

Consult official Analog Devices documentation for verified substitute part numbers. Cross-reference package dimensions and electrical ratings to ensure mechanical and functional compatibility without altering the protection characteristics of the original design.
