The component is also available in different package types like SOT-23,SOT-223, DIP, etc.

Types

The DZ2J12000L are available in three types:

• Zener Diodes: These diodes offer a wide voltage range from 2.4V to 200V and are used for regulating the voltage of a circuit by providing efficient power distribution.
• Schottky diodes: These diodes have a low forward voltage drop, high speed and low forward recovery time. They are used for protecting circuits from transient current.
• Silicon Avalanche Diodes: These diodes have low power dissipation, fast switching times and low breakdown voltage. They are used for limiting the transient current and providing solid state protection.

Application Field

The DZ2J12000L has various application fields. It is mainly used for power regulation in consumer electronics, automotive electronics, industrial and medical applications. It is also used for voltage regulation in PCs and laptops. Additionally, it can be used for transient voltage protection and voltage clamping in different systems. Some common applications include:

• Voltage regulation in computers, laptops and other consumer electronics.
• Transient protection in automotive, medical and industrial systems.
• Voltage clamping for protection in overload conditions.
• Power supply protection in high power systems.

Working Principle

The DZ2J12000L is composed of a single diode-zener diode. It works on the principle of reverse breakdown. When a reverse voltage is applied to the diode, electrons are emitted from the junction. These electrons collide with the positive charges in the junction and create an electron-hole pair. As the voltage increases, more electrons are emitted and the junction becomes more forward biased. The voltage at which the current starts to increase sharply is known as the Zener voltage. Beyond the Zener voltage, the current flow increases exponentially.

The DZ2J12000L also employs current limiting inductors, which allow the current to be limited to a certain maximum level. The inductors are connected in series with the diode and regulate the voltage at the diode. This prevents any spikes that might damage the diode. The diode also has ESD protection circuits and thermal shutdown circuits, which protect the diode from excessive current and heat.

Conclusion

The DZ2J12000L is an ideal component for a variety of applications such as voltage regulation, power protection and voltage clamping. It employs a single diode-Zener diode for power regulation and voltage protection. Additionally, it has current limiting inductors, ESD protection circuits and thermal shutdown circuits, which provide enhanced protection and reliability.
