Diodes - Zener - Single

BZX84C33VLFHT116 is a single Zener diode with a nominal break-down voltage of 4.7V. It is used to protect any application, such as a circuit board, from overvoltages from outside the circuit, commonly called transients. It also offers high surge capabilities that protect against damaging voltages, allowing normal circuit operation to continue when the surge is gone. In addition, it provides a reverse biasing flow of current, which helps protect the components of electronic circuits. The device is encapsulated in a SOD-323 package that offers low forward voltage and excellent thermal resistance. Its junction capacitance and reverse recovery time are very low, which makes it ideal for applications requiring high switching speeds or high-side drive. Its peak power dissipation of 600 mW and its thermal derating of 8 mW per °C make it suitable for applications operating with high temperatures.

Application Field

BZX84C33VLFHT116 can be used in several different applications where overvoltage protection is needed. It can be used, for example, in portable devices such as laptops, smartphones, and tablets that can be damaged by voltage surges due to the environment, making it suitable for battery-operated applications. It is also ideal for automotive applications that require hi-side MOSFET drive capability and over-voltage protection, such as high-performance audio systems and power supplies, since the device has a very low reverse recovery time. In addition, this diode can also be used in LCD screens, A/C systems, power supplies, LEDs, and other automotive applications.

Working Principle

BZX84C33VLFHT116 works in the same way as other Zener diodes. When a forward current is applied to the diode, it will act as a regular forward-biased diode and effectively block any current flowing in the reverse direction. However, when a reverse voltage is applied to the diode, it will exceed the diode\'s breakdown voltage and create a reverse current. The current across the junction is then limited by the Zener resistance. As a result, the device creates a well-defined voltage drop across its terminals, making it well-suited for stabilizing circuits and protecting them from overvoltages. The diode can also be used as a voltage reference by creating a path through which current can flow when a reverse voltage is applied. This allows the voltage across the diode to remain constant and provide a stable reference voltage over a wide range of temperatures and operating conditions. Furthermore, the device also has a fast response time that helps protect against short duration overvoltage events, such as electrical transients.

In addition to its voltage reference and overvoltage protection capabilities, BZX84C33VLFHT116 also offers excellent thermal performance and high peak power dissipation. It is also very small and has a low on-state voltage drop, making it suitable for high-speed operations. Finally, the device is also RoHS compliant and requires a very low forward current to operate.

Conclusion

Overall, BZX84C33VLFHT116 is an ideal choice for applications requiring robust overvoltage protection and high-side MOSFET drive capability. It has a very low forward voltage drop, a fast response time, and a high peak power dissipation, which make it suitable for many applications. It is also small, has excellent thermal performance, and is RoHS compliant, allowing designers to easily integrate it into their designs.
