LT4356HS-1#TRPBF

Overview

The LT4356HS-1#TRPBF is a board mount surge protector manufactured by Analog Devices Inc. It operates within a voltage range of 4 VDC to 80 VDC and features an SMD/SMT end type in an SOIC-16 package. The device has a maximum quiescent current rating of 40 uA and functions as a surge stopper. It supports PCB mounting with dimensions of 10 mm length, 3.99 mm width, and 1.75 mm height. The component is designed for industrial, automotive, and avionics applications, operating between -40 C and +125 C.

Feature Summary

• Provides on-board protection against electrical surges
• Integrates fault latchoff functionality for circuit isolation
• Supports high-voltage input ranges up to 80 VDC

Applications

• Automotive electronics systems
• Avionics power distribution
• Industrial equipment protection

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging rather than tube. Confirm the SOIC-16 package matches design requirements. Ensure the -40 C to +125 C temperature range aligns with environmental conditions. Cross-reference the datasheet for pinout compatibility.

Selection Notes

Select this component when high-voltage surge protection is required for sensitive loads. The SOIC-16 package offers a balance of thermal performance and footprint efficiency. Consider the 40 uA current consumption for low-power standby applications. Verify that the latchoff feature meets system reset logic requirements.
