LT4363IMS-2#TRPBF

Overview

The LT4363IMS-2#TRPBF is a high voltage surge stopper with current limit, manufactured by Analog Devices Inc. It operates within a supply voltage range of 4V to 80V and features an adjustable clamp voltage of 27V. The device is housed in a surface-mount MSOP12 package measuring 4.04mm x 3.00mm with a height of 1.10mm. It supports an operating temperature range from -40°C to +85°C and a storage temperature range from -65°C to +150°C. The component has a湿气敏感性等级 (MSL) of 1, indicating unlimited floor life. It is designed for automotive applications and is RoHS compliant.

Feature Summary

• Provides board mount surge protection with integrated current limiting capabilities
• Automatically retries operation after cool down delay following overvoltage or overcurrent events
• Includes shutdown pin functionality to inhibit retry if overvoltage exceeds specific thresholds

Applications

• Automotive systems requiring high voltage surge suppression
• Avionics power distribution networks
• Industrial control equipment protection

Procurement Notes

Verify the exact ordering suffix and package variant against official Analog Devices documentation before procurement. Confirm availability status as supply may be restricted. Ensure the selected part number matches the required operational temperature range and application specifications. Cross-reference datasheet parameters for electrical characteristics relevant to the specific system design requirements.

Selection Notes

Select this component when automatic retry behavior is preferred over latching shutdown modes. Consider the 27V adjustable clamp voltage for systems requiring specific transient protection levels. Evaluate the MSOP12 package dimensions for PCB layout constraints. Verify compatibility with automotive environmental standards and operating temperature ranges defined in the datasheet.

Part Context

The LT4363 series belongs to Analog Devices' lineup of high voltage surge stoppers. The LT4363-2 variant specifically offers automatic retry functionality, distinguishing it from the LT4363-1 which latches off. This family addresses the need for robust input protection in harsh electrical environments while maintaining system availability through self-recovery mechanisms.
