Diodes - Zener - Single

The PLZ3V9A-HG3/H is a general purpose, single-terminal, semi-conductive P-N junction diode otherwise known as a Zener diode. A Zener diode is a type of diode that’s specifically designed to be forward-biased and to regulate the voltage across its terminals. It’s able to do this by breaking down or “zenering” as the voltage applied across its terminals exceed a certain value.Due to the simple nature of the device and its unique characteristics, PLZ3V9A-HG3/H is widely used for many different applications. It’s often used for voltage regulation, signal processing, rectification, electrical isolation, and attenuation of radio frequency and audio signals. A Zener diode is commonly used as a voltage reference since it can provide a stable voltage, even when the input voltage changes.The working principle of a Zener diode is quite simple. It works by allowing current to flow in one direction and blocking current from flowing in the opposite direction. When the voltage across the Zener diode exceeds the breakdown voltage, also known as the Zener voltage, the internal resistance of the diode breaks down and then current is allowed to flow in the reverse direction. This results in a lower resistance and the Zener diode then acts as a voltage regulator.In the case of the PLZ3V9A-HG3/H, It’s often used for applications that require a constant voltage output with a precise voltage reference. Due to its simple design and minimal power requirements, it’s also a great choice for low-noise and low-power environments. Since it only needs to regulate a small amount of power, it’s also ideal for applications that need precise and reliable voltage regulation such as medical and industrial equipment.The PLZ3V9A-HG3/H is also designed to protect circuits from damage due to excessive current. It has a reverse breakdown voltage that typically ranges between 5 and 9.1 volts, depending on the model and its temperature coefficient is about -0.6mV/K, for a temperature range of -40 to +100 degrees Celsius. The diode has a maximum power dissipation of 500mW, a maximum reverse current of 1mA, and a maximum reverse energy of 5µJ. The PLZ3V9A-HG3/H is a reliable and cost-effective Zener diode that’s suitable for many different types of applications. It’s able to provide a stable voltage output and protect circuits from damage due to excessive current, making it a great choice for those who need a reliable voltage regulation solution.
