1N2806B Application Field and Working Principle

1N2806B belongs to a type of single Zener diodes that is becoming more commonly used in the modern day. It is commonly used in the electronic switches, instruments and adjust voltage regulator, among more other applications. The main principles driving the 1N2806B will be discussed in this article.

The Principle of Operation

At normal current flow, the 1N2806B operates as any other diode, allowing conventional flow in the forward direction. When a negative voltage is applied to the anode, if this voltage is higher than the junction voltage of the 1N2806B, current will begin to flow in the reverse direction. This is referred to as ‘Zener Breakdown’ and is the main principle of operation that the 1N2806B relies on. As the Zener breakdown current rises, the voltage across the diode will remain constant (The breakdown voltage is specified in the diode’s data sheet). The 1N2806B is designed to use the Zener effect for the purpose of voltage stabilization.
