LT4363MPMS-2#PBF

Overview

The LT4363MPMS-2#PBF is a board mount surge protector manufactured by Analog Devices Inc., designed for high-voltage applications. It operates within an input voltage range of 4 VDC to 80 VDC and features a current rating of 1.2 mA. The component is housed in an MSOP-12 surface-mount package with dimensions of 4 mm length, 3 mm width, and 0.86 mm height, weighing 270 mg. It supports an extended operating temperature range from -55°C to +125°C and utilizes SMD/SMT termination. This device belongs to the LT4363 series and is intended for use in automotive, avionics, and industrial environments.

Feature Summary

• Provides onboard protection against high-voltage surges with integrated current limiting capabilities
• Automatically retries operation after fault conditions cool down, unless overvoltage exceeds specific thresholds
• Designed for robust performance in demanding automotive, avionics, and industrial sectors

Applications

• Automotive electronic systems requiring surge protection
• Avionics equipment needing reliable high-voltage isolation
• Industrial control systems subject to transient voltage events

Procurement Notes

Verify availability status carefully as supply may be restricted or limited. Confirm that the MSOP-12 package matches your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Check RoHS compliance details if required by your manufacturing standards. Validate that the 4V to 80V input range aligns with your system design parameters before ordering.

Selection Notes

Select this component when high-voltage surge protection with automatic retry functionality is required. Consider the MSOP-12 package size for space-constrained designs. Verify compatibility with automotive, avionics, or industrial temperature ranges. Compare against other LT4363 variants if latch-off behavior is preferred over auto-retry. Ensure the 1.2 mA current rating suits your load requirements.

Part Context

This part belongs to the LT4363 series of high-voltage surge stoppers with current limit. It is produced by Analog Devices Inc. (formerly Linear Technology). The device is categorized under board mount surge protectors and surge suppressors. It is designed to protect downstream components from input voltage transients while managing current flow during fault conditions.

Replacement Considerations

LT4363IS-2#PBF offers similar functionality in a SOIC-16 package with different thermal and dimensional characteristics. LT4363IMS-2#TRPBF provides tape-and-reel packaging options. Verify pinout compatibility and package dimensions when substituting.
