The LT4356IS-3#PBF 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 a quiescent current rating of 30 uA. The component utilizes an SOIC-16 surface-mount package with dimensions of 10 mm length, 3.99 mm width, and 1.75 mm height. It supports PCB mounting and functions across a temperature range of -40 C to +85 C. This device serves as a surge stopper with fault latchoff capability.
Verify the specific suffix #PBF indicates lead-free packaging compliance when sourcing. Confirm the IS designation corresponds to the industrial temperature grade (-40 C to +85 C) rather than commercial or military variants. Ensure the SOIC-16 footprint matches the target PCB layout constraints before finalizing procurement orders.
Select this variant for designs requiring fault latchoff behavior to prevent automatic restart after surge events. Compare against LT4356CS-3#PBF if operating temperatures remain within commercial limits (0 C to +70 C). Consider LT4356CDE-3#PBF for space-constrained layouts utilizing DFN-12 packages instead of SOIC-16.
This component belongs to the LT4356-3 series of surge suppressors. It is part of Analog Devices' portfolio of board mount surge protectors designed to safeguard sensitive electronics from transient voltage events. The series includes various package options and temperature grades to suit different environmental requirements.
LT4356CS-3#PBF offers identical electrical performance but with a commercial temperature range. LT4356HMS-3#PBF provides similar functionality in a smaller MSOP-10 package with extended high-temperature capability up to +125 C.
