Working principle of JANTX1N3891A

The working principle of JANTX1N3891A is based on the PN junction of a diode. When a forward voltage is applied to the diode, the electrons in the material move and recombine with the holes in the material. This current flows from the anode to the cathode and the voltage drops. This is known as the forward voltage drop. When reverse voltage is applied, the current will not pass, this is known as the reverse bias.

The reverse leakage current is the amount of current that flows through the diode when the reverse voltage is applied. This current is typically low due to the PN junction blocking the current. The forward voltage of the diode is typically between 0.4 and 0.8 volts, depending on the type of diode. The JANTX1N3891A diode has a forward voltage drop of 0.8 volts. The reverse current is typically between 0.1 and 1 microamps.

Due to its low forward voltage drop and high stability, the JANTX1N3891A is a suitable choice for high power applications. It is a low cost and reliable option for these types of applications. The diode can be used for a variety of purposes such as rectifying AC current, controlling current flow in switching power supplies, and protecting other components.
