LTC4368HDD-2#PBF

Surge Suppression ICS Overview

The LTC4368HDD-2#PBF is a board mount surge protector manufactured by Analog Devices Inc., designed for UV/OV and reverse protection control with bidirectional capabilities. It operates within a voltage range of 2.5 VDC to 60 VDC, drawing a maximum current of 100 uA. The component functions reliably across an extended temperature spectrum from -40°C to +125°C. Housed in a compact DFN-10 package measuring 3 mm x 3 mm with a height of 0.75 mm, it utilizes SMD/SMT termination. This device belongs to the LTC4368 series and is classified under surge suppressors.

Surge Suppression ICS Procurement Notes

Verify component authenticity through authorized channels due to restricted supply status. Confirm package integrity upon receipt, as the DFN-10 form factor requires careful handling. Ensure design compatibility with the specified 2.5 VDC to 60 VDC operating range before implementation. Cross-reference datasheet specifications against current project requirements to validate performance parameters.

Surge Suppression ICS Selection Notes

Select this controller when bidirectional surge protection is required for high-voltage bus lines. The adjustable clamping feature allows customization for specific system thresholds. Consider the DFN-10 footprint constraints during PCB layout. Evaluate thermal management needs given the -40°C to +125°C operational range. Compare against non-bidirectional alternatives if unidirectional protection suffices for the application.
