LTC4368HMS-2#WPBF

Surge Suppression ICS Overview

The LTC4368HMS-2#WPBF is a board mount surge protector manufactured by Analog Devices Inc., designed for automotive, energy storage, industrial, and portable instrumentation applications. It functions as an UV/OV and reverse protection controller with a bidirectional circuit breaker. The device operates within a voltage rating of 2.5 VDC to 60 VDC and has a current rating of 100 uA. It utilizes SMD/SMT termination in an MSOP-10 package measuring 3 mm x 3 mm x 0.86 mm. The component supports a minimum operating temperature of -40 C and a maximum of +125 C.

Surge Suppression ICS Feature Summary

• Provides bidirectional circuit breaker functionality for overcurrent fault protection in both forward and reverse directions.
• Integrates under-voltage and over-voltage protection controllers to safeguard against power supply anomalies.
• Supports negative input voltage conditions to prevent damage from incorrect polarity connections.

Surge Suppression ICS Applications

• Automotive systems
• Energy storage systems
• Industrial equipment
• Portable instrumentation

Surge Suppression ICS Procurement Notes

Verify the specific suffix #WPBF confirms lead-free and RoHS compliance status through official Analog Devices documentation. Confirm the MSOP-10 package dimensions and thermal characteristics match the target PCB layout requirements. Ensure the 2.5 V to 60 V input range aligns with the system's operational voltage profile. Cross-reference the datasheet for any recent product change notices affecting pinout or electrical specifications.

Surge Suppression ICS Selection Notes

Select this component when bidirectional surge protection and reverse polarity handling are required in compact designs. The MSOP-10 package suits space-constrained automotive and industrial boards. Verify that the 100 uA current rating meets the control circuit needs. Consider the -40 C to +125 C temperature range for harsh environment reliability. Compare against similar models like the IMS variant if different packaging is preferred.

Surge Suppression ICS Part Context

This part belongs to the LTC4368 series of Surge Stoppers from Analog Devices. It is specifically engineered to protect downstream electronics from power supply faults. The HMS-2 designation indicates a high-temperature extended version in an MSOP package. It complements other power management ICs by providing robust input stage protection.

Surge Suppression ICS Replacement Considerations

The LTC4368IMS-2#WPBF is a direct package alternative within the same functional family. Verify pin compatibility and thermal performance differences between the HMS and IMS variants before substitution. Consult the official selector guide for exact electrical equivalence.
