LT4363CS-1#PBF

Overview

The LT4363CS-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 V to 80 V DC and features a quiescent current of 700 uA. The device is housed in a 16-pin SOIC package with SMD/SMT termination. It supports an operating temperature range from 0°C to +70°C. Designed for board mount applications, it provides protection against overvoltage and overcurrent conditions by latching off after a timer delay.

Feature Summary

• Integrates high voltage surge stopping capability with internal current limiting to protect downstream components from output overloads.
• Features automatic latch-off behavior upon sustained overvoltage or overcurrent events, requiring external reset via the SHDN pin.

Applications

• Automotive systems
• Avionics equipment
• Industrial control units

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm RoHS compliance status and check for specific manufacturing date codes relevant to your production timeline. Ensure the SOIC-16 package dimensions match your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this part when designing circuits requiring robust protection against high voltage transients up to 80V. Consider the 700 uA quiescent current draw for power-sensitive designs. Verify that the commercial temperature range (0°C to +70°C) meets environmental constraints. Compare with LT4363MPMS-1#PBF if extended industrial temperature ranges are required.

Part Context

This component belongs to the LT4363 series of high voltage surge stoppers. It is distinct from the LTC4364 series which includes ideal diode functionality. The CS suffix indicates a commercial grade temperature rating and SOIC-16 packaging, differentiating it from military or wider temperature variants within the same family.

Replacement Considerations

LT4363MPMS-1#PBF offers similar functionality but in an MSOP-12 package with an extended temperature range (-55°C to +125°C). Verify pin compatibility and thermal performance differences before substitution.
