BZT585B22T-7

Diodes - Zener - Single

BZT585B22T-7 is a single zener diode designed to work in a wide range of applications. It has an average forward voltage drop of less than 0.3V at a specified current and a maximum reverse leakage current of either 5mA or 10mA.

This diode can be used both in linear and nonswitching applications. It has a wide operating temperature range from -40°C to +130°C and it can be used in a variety of applications, but it is mainly used for voltage regulation, transient suppression and dynamic clamping.

The BZT585B22T-7 diode has a relatively low price per unit compared to other zener diodes and is therefore often specified for applications where cost is an important factor. It is also a very reliable zener diode, with a mean time between failures of over 10,000 hours.

Working Principle

The BZT585B22T-7 diode works on the principle of Zener breakdown. When a reverse voltage is applied across the diode, electrons in the diode material move to higher energy levels due to repulsive forces created by the electric field. When this threshold is crossed, the electrons start to break down the barrier and cause a avalanche effect, stopping when the voltage drops to a desired level. This process is known as Zener breakdown, and the desired voltage level can be accurately tuned by changing the doping levels of the material in the diode.

The zener diode also functions as a rectifier in linear applications. When a voltage is applied across the diode, it acts as a normal diode, allowing current to flow in one direction only. This allows the diode to act as a current limiter and protect other components in the circuit.

Application Fields

The range of applications where the BZT585B22T-7 can be used is quite broad. It is mainly used for voltage regulation, transient suppression and dynamic clamping. It can also be used as an overvoltage protection device, to limit the maximum voltage in a circuit or as an emergency power switch. In addition, it can also be used for power conditioning and for AC/DC and DC/DC conversion.

The BZT585B22T-7 is also commonly used in data processing, communication systems and medical equipment. It can be used to regulate voltage and current in these devices, protect against overvoltage, and provide temporary power in emergency situations. It is also used in automotive systems, where its low price per unit makes it an attractive option.

In conclusion, the BZT585B22T-7 is a reliable and affordable zener diode with a wide range of applications. It works on the principle of Zener breakdown and can be used in linear and non-switching applications. It is mainly used for voltage regulation, transient suppression and dynamic clamping, but it can also be used as an overvoltage protection device, an emergency power switch and for power conditioning.
