The ON Semiconductor 1N5345BRLG is a single, commonly used, axial-lead diode. It is designed to provide efficient reverse polarity protection for 12 volt electrical systems. With a maximum peak repetitive reverse voltage of 50 volts, it can handle higher transient power than many 12 volt devices. In addition, the 1N5345BRLG has a low forward voltage drop of less than 0.6 volts, which ensures that the device remains cool even when carrying high currents.
