Hi there! this may not be the right place to ask but I have an SMD component that I need identifying that looks like an SMD diode with the code SM4B across the top. Does anyone have any idea where to get one from because from my research today I cannot find a matching component.
The bonus is only one of the four I have on a small PCB I'm trying to repair has popped so if needed I can test the other three to find an equivalent component.
The kicker ... I have no schematics of the PCB in question yet and even then I doubt I will get a response from the company who manufactured the board.
Any help is welcome guys and thanks in advance.
