TLZ30C-GS18

Zener diodes are a wide family of diodes that are specifically designed to provide a regulated voltage reference. They are used to stabilize voltages and protect sensitive components from destructive voltage spikes. The TLZ30C-GS18 is a single Zener diode that is popular in many applications. This article will discuss the application field and working principle of the TLZ30C-GS18.

Application Fields

The TLZ30C-GS18 is designed for low to medium power stabilization applications. It is a 40V Zener diode with a maximum power dissipation of 500mW, making it suitable for applications that require a moderate voltage drop. Common applications of the TLZ30C-GS18 include:

• Use in low voltage power supplies to rectify AC current.
• Providing reference voltages in logic circuits.
• Protecting components from high voltage spikes.
• Stabilizing low voltage power supplies.

The TLZ30C-GS18 is popular for its low leakage current and good temperature coefficients. It is fairly inexpensive and has a long lifetime, making it a cost-effective choice for many applications. It is commonly used in low voltage applications such as automotive, industrial, and consumer electronics.

Working Principle

The function of a Zener diode is to provide a voltage reference. This means that it will allow current to flow in one direction (the “Zener breakdown”) until a certain voltage level is reached. In the case of the TLZ30C-GS18, the Zener voltage is 40V. Once the voltage reaches 40V, the diode begins to conduct current in both directions (forward and reverse) which provides the voltage regulation.

In order for the TLZ30C-GS18 to function, it needs to be connected in reverse bias. This means that the anode must be connected to the lower voltage and the cathode must be connected to the higher voltage. Once the voltage reaches the breakdown voltage of 40V, it will begin to conduct current in both directions. This ensures that the voltage stays constant at 40V, which allows it to be used as a reference voltage.

The TLZ30C-GS18 is a good choice for low and medium power applications due to its low power dissipation and good temperature coefficients. It is also relatively inexpensive, and its long lifetime makes it a cost-effective choice for many applications.

Conclusion

The TLZ30C-GS18 is a low to medium power Zener diode that is popular for its low leakage current and good temperature coefficients. It is mainly used for voltage stabilization and protection from voltage spikes. It is also a cost-effective and long-lasting choice for many common low voltage applications.
