PDZ11B -115 Diodes - Zener - Single Application Field and Working Principle

The PDZ11B-115 is a zener diode with a single working principle and many applications in industrial, commercial and military applications. It is a two lead semiconductor device that is designed to regulate voltages by maintaining a constant voltage drop across its two leads when connected in an AC or DC circuit. It can be used in the voltage regulator of a circuit, for an ESD protection, and for reverse polarity protection.

Types of Zener Diodes

The PDZ11B-115 is one of several different types of Zener diodes available, including the dual and reverse breakdown variety. Generally, the dual breakdown type will have two different breakdown voltages, while the reverse breakdown type will only have one breakdown voltage. The PDZ11B-115 is a single breakdown type, meaning it has only one breakdown voltage.

Specification

The PDZ11B-115 has a breakdown voltage of 115V, with a rated power of 500mW, a forward voltage drop of 0.7V, and a reverse current of 0.0003A up to its rated power. It is a one piece diode, with a very low capacitance, and it is rated for high temperature and humidity operation.

Applications

One of the primary applications for the PDZ11B-115 is for voltage regulation in DC circuits. It can be used for controlling the output voltage of a DC power supply, or for providing a uniform output voltage from multiple power sources. It can also be used for preventing input voltage from exceeding certain limits in electronics. Another common application of PDZ11B-115 is for providing protection in power supplies, such as preventing reverse voltage, or protecting against transients. It can also be used for preventing ESD (electrostatic discharge) in electronics and power supplies, as it helps to limit the peak voltages and currents in the circuit.

Working Principle

In DC circuits, the PDZ11B-115 acts as a zener diode, which works by allowing current to flow in one direction only. It basically maintains a constant voltage across its two leads, regardless of the input voltage. When the input voltage is higher than the breakdown voltage (115V in the case of the PDZ11B-115), the diode will conduct current and pass it through to the output, thus regulating the output voltage. This is done by creating a voltage drop of 0.7V across the diode when it is conducting current, which is maintained regardless of the input voltage. This is because the diode\'s reverse current remains constant, even if the forward current increases. Furthermore, the PDZ11B-115 also has a very low capacitance, which further helps to improve its efficiency in maintaining a constant voltage.In summary, the PDZ11B-115 is a single breakdown zener diode, with a breakdown voltage of 115V, that can be used for voltage regulation and protection against reverse voltages and ESD. It has a rated power of 500mW, a 0.7V forward voltage drop, and a reverse current of 0.0003A.
