Working Principle of SZBZX84C18LT3G

The SZBZX84C18LT3G Zener diode is designed to conduct current in the forward direction and offer an impedance to current flow when it is reverse biased. The major characteristic of this diode is the reverse breakdown voltage, where its internal resistance abruptly changes. At this reverse breakdown voltage, a sudden surge of current is passed.

This diode has a relatively low breakdown voltage, which helps it reach a higher reverse current flow than other diodes. While it has a low voltage breakdown, its reverse current is quite low, which makes it ideal for power applications. The internal resistance of the diode remains stable until the breakdown voltage is reached, at which point the internal resistance drops drastically.

The low breakdown voltage and reverse current of the SZBZX84C18LT3G make it more efficient and reliable than other Zener diodes when designed for power applications. Due to the high reverse breakdown voltage, some slight voltage fluctuations around this point do not affect its working efficiency. As a result, it can be used in a wide range of different applications in order to provide a stable level of protection.

Conclusion

The SZBZX84C18LT3G Zener diode is a single diode and is rated at 18 Volts reverse voltage and 3 Watts of power. This diode is an economic choice for reverse voltage protection and other power applications. It features low noise operation, constant output voltage in power supply systems, and load-leveling systems. The low breakdown voltage and reverse current make the diode more efficient and reliable than other Zener diodes for power applications. Overall, this diode is an ideal choice for a variety of different applications.
