LT4363MPS-2#PBF

Overview

The LT4363MPS-2#PBF is a high-voltage surge stopper with current limit, manufactured by Analog Devices Inc. It operates within an input voltage range of 4 VDC to 80 VDC and features a maximum operating temperature of +125°C and a minimum of -55°C. The device is housed in a SOIC-16 surface-mount package with dimensions of 10 mm length, 3.99 mm width, and 1.75 mm height. It is designed for robust protection against sustained overvoltage or overcurrent conditions.

Feature Summary

• Provides high-voltage surge stopping capability with integrated current limiting to protect downstream components from overload damage.
• Features automatic retry functionality after fault conditions cool down, ensuring system recovery without manual intervention.
• Includes latch-off reset capability via the SHDN pin for applications requiring controlled shutdown states.

Applications

• Automotive power systems
• Avionics equipment
• Industrial control circuits

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm the SOIC-16 package variant matches the design footprint requirements. Ensure the 80VDC rating aligns with the target application's transient survival specifications. Check for any recent manufacturing changes that may affect compatibility.

Selection Notes

Select this component when high-voltage input protection up to 80VDC is required alongside precise current limiting. The automatic retry feature suits applications needing continuous operation after transient faults. Consider the SOIC-16 package for PCB space constraints compared to other variants like MSOP-12. Evaluate thermal performance within the -55°C to +125°C operating range.

Part Context

This part belongs to the LT4363 series of high-voltage surge stoppers. It complements other variants such as LT4363MPMS-2#PBF (MSOP-12) and LT4363HMS-2#PBF (MSOP). The series is designed for protecting sensitive electronics from input surges and overcurrent events in demanding environments.

Replacement Considerations

LT4363MPMS-2#PBF offers identical functionality in an MSOP-12 package. LT4363HMS-2#PBF provides similar features in a different MSOP variant. Verify pinout and package dimensions when substituting to ensure mechanical compatibility.
