LT4363MPS-1#PBF

Overview

The LT4363MPS-1#PBF is a high voltage surge stopper with current limit, manufactured by Analog Devices Inc. It operates within an input supply range of 4 VDC to 80 VDC and features an SMD/SMT package type. The component is housed in a SOIC-16 box/box configuration with dimensions of 10 mm length, 3.99 mm width, and 1.75 mm height. It supports a minimum operating temperature of -55°C and a maximum of +125°C. The device is designed for board mount applications and includes a tube packaging option.

Feature Summary

• Provides integrated protection against high voltage surges and overcurrent conditions on the input line.
• Features automatic retry or latch-off behavior upon fault detection to protect downstream circuitry.
• Includes internal current limiting to safeguard the series pass MOSFET during output overload events.

Applications

• Automotive systems requiring robust input protection
• Avionics equipment needing reliable surge suppression
• Industrial control panels exposed to transient voltages

Procurement Notes

Verify the specific suffix MPS-1 against the official Analog Devices datasheet to confirm pinout and functional compatibility. Ensure the SOIC-16 package dimensions align with your PCB footprint requirements. Confirm that the -55°C to +125°C temperature range meets your environmental specifications. Check for any recent Product Change Notifications (PCNs) regarding manufacturing changes.

Selection Notes

Select this component when high voltage input protection is required for sensitive loads. Compare the LT4363MPS-1#PBF with other variants like the LT4363IDE-1#PBF based on package size and thermal performance. Consider the automatic retry feature if system availability is critical after transient faults. Evaluate the current limit settings against your load requirements to ensure adequate protection without nuisance tripping.

Part Context

The LT4363 series consists of high voltage surge stoppers designed to protect downstream components from input transients. The MPS variant specifically utilizes a SOIC-16 package, offering a balance between thermal dissipation and board space efficiency compared to smaller packages. It is part of Analog Devices' portfolio for power management and protection solutions.
