LTC4364HS-1#PBF

Overview

The LTC4364HS-1#PBF is a board-mount surge stopper manufactured by Analog Devices Inc., designed for robust overvoltage and surge protection in high-voltage systems. It operates within a voltage range of 4 VDC to 80 VDC and features an adjustable clamping voltage mechanism. The device utilizes an external switch topology, allowing for flexible integration with various power stages. Packaged in a SOIC-16 surface-mount format, it supports operation across an extended temperature range from -40°C to +125°C. With a quiescent current of 750 uA, this component provides reliable circuit protection for demanding industrial and automotive applications.

Feature Summary

• Provides integrated surge suppression and overvoltage protection for high-voltage DC lines
• Features adjustable clamping voltage capability to accommodate diverse system requirements
• Utilizes an external switch architecture for enhanced control and flexibility
• Designed for wide operating temperature ranges suitable for harsh environments

Applications

• Automotive electronic systems requiring high-voltage surge protection
• Avionics equipment needing reliable overvoltage safeguards
• Industrial machinery and control systems exposed to electrical transients

Procurement Notes

Verify the specific suffix and package type against project requirements before ordering. Confirm that the SOIC-16 footprint matches the PCB layout design. Ensure compatibility with the intended external switching components. Check for any recent product change notifications regarding manufacturing sites or material composition updates. Validate supply chain availability through authorized distributors to guarantee authenticity.

Selection Notes

Choose this component when designing circuits that require protection against high-voltage surges up to 80V. The adjustable clamping feature allows customization for specific threshold needs. Consider the SOIC-16 package size for space-constrained designs. Evaluate the 750 uA quiescent current impact on overall system efficiency. Ensure the external switch selection aligns with the thermal and current capabilities required for the application environment.

Part Context

This part belongs to the LTC4364 series of Surge Stoppers, which are specialized integrated circuits for protecting sensitive electronics from voltage spikes. The HS-1 variant specifically denotes the SOIC-16 package and the first version of the adjustable clamp functionality. It complements other variants like the IMS-1 (MSOP package) and IDE-2 (eval board context), offering a standard surface-mount solution for industrial-grade protection scenarios.

Replacement Considerations

LTC4364IMS-1#PBF offers identical electrical performance in a smaller MSOP-16 package. LTC4364HS-2#PBF may be considered if different pinout or specific internal configuration variations are required, though datasheet verification is essential. No direct drop-in replacements exist without verifying package and pin compatibility.
