Diodes - Zener - Single

1N968B is a dual Zener diode, which is a type of diode optimized to produce a specific voltage drop when reverse-biased. As such, it is frequently used to maintain a stable voltage level in an electrical circuit. The 1N968B component consists of two Zener diodes in a single package, allowing for more compact applications.

Application Field:

1N968B can be used in various applications, including the overvoltage protection of low-voltage power supply circuits, the fixation of voltage levels in audio and communication circuits, and for suppressing inductive flyback spikes in solenoid drivers. In addition, 1N968B can be used as DC voltage stabilizers and for switching circuits. It can also be used in applications where specific voltage references are needed, such as battery or solar chargers.

Working Principle:

1N968B is designed to operate at a specified voltage known as the Zener voltage. It is constructed with a higher doping level in the heavily doped p-type anode and the heavily doped n-type cathode, resulting in lower resistance than a normal diode. When a reverse bias voltage is applied to the 1N968B, an electric field is created in the depletion region, allowing current to flow and generating a reverse breakdown voltage across the terminals. The breakdown voltage is determined by the doping levels and is consistent in nature.

When the voltage on the diode exceeds the Zener voltage, a reverse current flows through the diode and a Zener diode breakdown occurs. This effect is used as a voltage regulator in series with a load, forming a DC voltage regulator. As the voltage fades, it is automatically adjusted to the specified value through the feedback loop. The 1N968B provides remarkable stability in most applications without additional components.

In addition, 1N968B has excellent temperature stability and surge capabilities, which makes the device suitable for transient processing applications; it also has low operating current and low thermal radiation, allowing it to be used in a variety of environments.

In conclusion, 1N968B is a dual Zener diode that is specifically designed to maintain a stable voltage level in an electrical circuit. It is capable of producing a specific voltage drop when reverse-biased and is mainly used for overvoltage protection, voltage regulation, and other related applications.
