It has an operating temperature range of -55° C to +150° C and a junction capacitance of 100 pF. It can also handle up to 1A current. The diode has a maximum reverse voltage of 200V and a forward voltage of 0.1V.

Application Field

The PLZ18A-G3/H is primarily used in power switching and protection applications. It can be used in a wide range of fields, such as automotive, industrial, military and aerospace, to control and protect circuits against power supplies and voltage spikes. Additionally, it can be used to limit the voltage output in applications like voltage regulators and voltage clamps.

Working Principle

The working principle of a PLZ18A-G3/H is based on the principles of classical Zener Diodes. In essence, the diode has a built-in reverse bias voltage, so that when the voltage through the diode exceeds the reverse bias voltage, the diode will conduct current. This process is known as breakdown, and the amount of current will be determined by the breakdown voltage.Furthermore, due to the properties of the diode, when the forward current is increased, the diode will start conducting, and when the current is reduced, the diode will stop conducting. This creates a voltage regulating effect, and is used in applications like voltage regulators and voltage clamps.

Advantages

One of the most attractive advantages of the PLZ18A-G3/H is its compact size. It is much smaller than many traditional metal-oxide-semiconductor (MOS) devices, making it easier to integrate into more complex system designs. Furthermore, the small size and power consumption of the device make it an ideal choice for battery-powered applications.The PLZ18A-G3/H also has a high level of reliability, due to its low power consumption and efficient operation. Additionally, it is able to handle high voltage and current, and is able to withstand intense environmental conditions.

Conclusion

In conclusion, the PLZ18A-G3/H is a single Zener diode, designed for power switching and protection applications. It has a breakdown voltage of 18 V, a maximum power dissipation of 200 mW and a junction capacitance of 100 pF. Furthermore, the PLZ18A-G3/H offers a range of advantages, including its compact size, low power consumption, high reliability and the ability to handle high voltage and current.
