LTC4380IMS-4#TRPBF

Overview

The LTC4380IMS-4#TRPBF is a low quiescent current surge stopper manufactured by Analog Devices Inc. Designed for board mount applications, it protects loads from high voltage transients up to 72 VDC. The device operates within a temperature range of -40°C to +85°C and features SMD/SMT termination in an MSOP-10 package measuring 3 mm x 3 mm with a height of 0.86 mm. It draws a typical operating current of 12 µA. This component is intended for automotive, avionics, and industrial environments requiring robust overvoltage protection.

Feature Summary

• Clamps gate voltage of external N-channel MOSFETs to limit output voltage during overvoltage events such as load dump
• Provides reverse input protection by driving back-to-back MOSFETs without Schottky diode voltage drop
• Includes internal multiplier for overcurrent protection based on MOSFET stress limits

Applications

• Automotive load dump protection
• Avionics power system transient suppression
• Industrial equipment surge protection

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the IMS-4 designation corresponds to the fixed clamp voltage variant required for the target system architecture. Ensure compatibility with the MSOP-10 footprint and thermal requirements for the intended operating environment.

Selection Notes

Select this part for systems requiring low static current consumption during always-on or battery-powered operation. Choose the fixed clamp version only if the application matches the specific voltage rating associated with the IMS-4 suffix. Consider the DFN package options if a smaller footprint is necessary for the design constraints.

Part Context

This component belongs to the LTC4380 series of low quiescent current surge stoppers. The series provides comprehensive protection against high voltage transients and overcurrent conditions using an external N-channel MOSFET. The family supports various packaging options including MSOP and DFN to suit different board space requirements.

Replacement Considerations

LTC4380IMS-4#PBF offers identical electrical specifications in tube packaging instead of tape and reel.
