The 1N2979B is a Zener diode that is frequently used in electronics. It is categorised as a Single Zener Diode and comes in a range of packages, including a TO-3 PIN package which has a maximum dissipation of 1.5 Watts. Typically, these diodes are used in power supplies to provide voltage regulation, clipping, and clamping, as well as for protection against overvoltages.

The 1N2979Bis a single Zener diode that features two metal layers which form a barrier between two pieces of semiconductor material. These two layers help to control the energy flow, allowing the diode to operate in a reverse voltage state while not permitting the current to flow in the forward direction.

The diode is made up of two different layers which are both P-type and N-type materials. In the case of the 1N2979B, the P-type layer is doped with more impurities than the N-type layer which helps to produce its Zener characteristics.

The 1N2979B’s application field is quite wide. It can be used to limit overvoltage surge protection, clipping, and clamping, as well as to regulate outputs in power supplies. It can also be used in a variety of different rectifiers and switch-mode power supplies (SMPS).

The working principle of the 1N2979B is fairly simple. When operated in reverse voltage (reverse of the forward biasing voltage across the diode junction), the diode breaks down and conducts. This results in a greater current flow than the forward biasing voltage would have allowed. As the voltage increases, the current through the diode also increases in a controlled manner, as per Zener’s Law.

The 1N2979B is a highly effective diode for a variety of applications and is becoming more and more popular with engineers and hobbyists alike. It can be used in both traditional designs as well as more modern circuits and is an ideal choice for voltage regulation, clipping, and clamping.
