LT4363IS-1#TRPBF

Overview

The LT4363IS-1#TRPBF is a high voltage surge stopper with current limit designed to protect loads from high voltage transients. It operates within a voltage range of 4 VDC to 80 VDC and features a circuit breaker threshold of 50mV. The device regulates output during overvoltage events and provides reverse input protection. It is housed in a 16-SOIC surface-mount package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides board-level protection against high voltage transients and surges
• Integrates current limiting functionality to prevent overload conditions
• Regulates output voltage during overvoltage events to safeguard downstream components

Applications

• Automotive electronic systems
• Avionics power distribution networks
• Industrial control equipment

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm that the IS-1 variant corresponds to the industrial temperature grade (-40°C to +85°C) and SOIC-16 package. Ensure compatibility with system voltage requirements up to 80 VDC before integration.

Selection Notes

Select this component for applications requiring integrated surge suppression and current limiting in high-voltage environments. The SOIC-16 package suits space-constrained PCB layouts. Consider the 50mV threshold for precise current monitoring needs. Verify thermal performance within the specified -40°C to +85°C operational range for reliability.

Part Context

This part belongs to the LT4363 series of high voltage surge stoppers manufactured by Analog Devices Inc. (formerly Linear Technology). The series focuses on protecting sensitive loads from transient voltage spikes and overcurrent conditions without external discrete components, offering a compact solution for power management.

Replacement Considerations

LT4363IS-2#TRPBF offers similar functionality but may differ in specific current limit thresholds or internal MOSFET characteristics. Verify pinout compatibility and electrical parameter alignment before substitution.
