LT4363IS-2#TRPBF

Overview

The LT4363IS-2#TRPBF is a board mount surge protector manufactured by Analog Devices Inc., belonging to the LT4363 series. It operates within a voltage range of 4 VDC to 80 VDC and features an SMD/SMT termination type in an SOIC-16 package. The device has a current rating of 1.2 mA and functions as a high-voltage surge stopper with current limiting capabilities. It supports PCB mounting and is designed for automotive, avionics, and industrial applications. The component operates between -40°C and +85°C.

Feature Summary

• Provides high-voltage surge protection with integrated current limiting
• Automatically retries operation after cool-down delay following overvoltage or overcurrent events
• Inhibits retry if output voltage exceeds specific threshold levels

Applications

• Automotive systems
• Avionics equipment
• Industrial control circuits

Procurement Notes

Verify that the suffix TRPBF indicates tape-and-reel packaging rather than tube packaging when sourcing this specific part number. Confirm RoHS compliance status through official documentation. Ensure the SOIC-16 package variant matches design requirements. Check availability constraints as supply may be limited. Validate that the automatic retry functionality aligns with system safety protocols before integration.

Selection Notes

Select this component for applications requiring robust input protection against transient voltages up to 80VDC. The automatic retry feature distinguishes it from latching variants, making it suitable for systems needing self-recovery without manual intervention. Consider the SOIC-16 package size for space-constrained designs. Verify thermal performance within the specified operating temperature range of -40°C to +85°C for environmental compatibility.

Part Context

This part belongs to the LT4363 family of high-voltage surge stoppers. It shares core functionality with other variants like LT4363IS-2#PBF but differs in packaging format. The '2' suffix denotes the automatic retry behavior, contrasting with latching versions. It complements power management solutions by safeguarding downstream components from input surges in critical infrastructure.

Replacement Considerations

LT4363IS-2#PBF serves as a direct physical substitute differing only in tube versus reel packaging.
