hey guys, i have a burned PCB board that someone asked me to repair..
so after about 2 hours of fixing and repairing most of it, and i found that i have a Diode Bridge that 2 of the Diodes is borken
both of them passing flow for both sides.
so the question is; why is that happen? too much AMP or Voltage, or heat?
what makes cause of that flow issue?
A diode has a set breakdown voltage, which is specified in the diode's datasheet. Breakdown is most often caused by over-voltage, but over-current can cause the diode to overheat and that can also cause it to conduct in both directions.
