LTC4380HMS-4#WTRPBF

Overview

The LTC4380HMS-4#WTRPBF is a low quiescent current surge stopper manufactured by Analog Devices Inc. It operates within a voltage range of 4 V to 72 V and features a maximum quiescent current of 8 uA during operation. The component is housed in an MSOP-10 package with SMD/SMT termination, measuring 3 mm in length and width, and 0.86 mm in height. It supports PCB mount installation and functions across a temperature range from -40 C to +125 C. The device is AEC-Q100 qualified for automotive applications.

Feature Summary

• Provides board mount surge protection using low quiescent current technology
• Capable of withstanding high surge voltages up to the MOSFET limit
• Includes overcurrent protection and reverse input protection down to -60V

Applications

• Automotive systems
• Avionics equipment
• Industrial control units

Procurement Notes

Verify the specific suffix #WTRPBF indicates tape and reel packaging configuration distinct from tube variants. Confirm AEC-Q100 qualification status matches project requirements. Ensure the MSOP-10 footprint aligns with existing PCB layout constraints. Validate that the 4 V to 72 V operating range covers all expected line conditions.

Selection Notes

Select this part when ultra-low standby power consumption is critical alongside robust surge handling capabilities. The integrated design eliminates the need for external discrete components typically required for basic surge suppression. Consider the wide operating temperature range suitable for harsh environments. Verify compatibility with external N-channel MOSFETs for optimal performance.

Part Context

This component belongs to the LTC4380 series of ideal diode controllers and surge stoppers. It is designed to protect sensitive downstream electronics from transient voltage spikes on power lines. The series offers various package options and voltage ratings to suit different system architectures and space limitations.
