Stays at 3840x2160 at 60Hz. In this case, the diode will exhibit a small resistance in both directions. Hello Chris, hope you are still around. Close-up of an EFD108 germanium point-contact diode in DO7 glass package, showing the sharp metal wire (cat whisker) that forms the semiconductor junction. As both of them travel towards the junction, holes and electrons recombine with each other to neutralize and forms ions. The common reasons for a diode failure are excessive forward current and a large reverse voltage. As opposite charges attract, few holes in P-type tend to go to n-side, whereas few electrons in N-type tend to go to P-side. Things I have done: To verify the contention made in a recent answer to another question, I applied a high voltage pulse without current limiting, using a capacitor bank, first to a couple of no-name LEDs, once forward and once in reverse bias, and later did the same to a couple of 1n4148 diodes. He managed to get a new replacement monitor (eventually) because, like me, the monitor is less than a week old. It is used in wave shaping, clamping, protection circuit and the main application of a Signal Diode is a Flyback Diode or Freewheeling Diode.We will see about 1N4148, a very commonly used Silicon Switching Signal Diode, its V-I Characteristics and few important specifications.
