Diodes - Zener - Single

The BZX884-B20,315 is a single Zener diode capable of withstanding high power dissipation levels. It is designed to provide a high degree of repetitive avalanche and Zener current clamping. It offers stable Zenerregulation and low leakage current. This diode offers excellent temperature stability, making it an excellent choice for applications requiring high levels of thermal efficiency.

This diode can be used in a wide range of applications including in television and video switching, power conditioning and supply regulation, industrial instrumentation, AC to DC conversion, and switching regulators.

The BZX884-B20,315 has an avalanche voltage rating of 30V, a reverse leakage current of 2mA, and a power dissipation rating of 0.5W. This diode features a low capacitance and a fast switching action. It is also able to handle reverse voltage transients up to 200V with a highly reliable Zener breakdown specification.

The BZX884-B20,315 is a two-pin single Zener diode which allows for easy mounting on a PCB. The two pins are equidistant from each other and connected to a wide variety of different circuit boards. The leads are usually constructed from copper with flat ends for easy insertion.

The basic principle ofoperation of the BZX884-B20,315 is as follows: As current begins to flow, the voltage drop across the device increases linearly with the current until the Zenervoltage is reached. At this point, the current will begin to increase sharply creating the characteristic Zener voltage “knee”. When the Zener voltage is exceeded, a significant energy is released and current will increase rapidly and continue to increase linearly with a higher Zener voltage. This current surge is known as the Zener avalanche.

The BZX884-B20,315 can be used as a voltage regulator, providing a stable operating voltage in the face of varying load conditions. By adding a resistor and/or capacitor, the operating voltage can be adjusted to compensate for changes in the input voltage. This can help reduce power consumption and further improve the efficiency of the system.

The BZX884-B20,315 is also often used as a clamping device in power supplies, providing protection against excessive voltage transients. When the voltage increase, the Zener diode conducts, clamping the voltage and limiting the potentially damaging transients.

In conclusion, the BZX884-B20,315 is a single Zener diode designed for use in a wide range of applications. It is capable of withstanding high power dissipation levels, providing a constant and stable operating voltage, and clamping voltage transients. Its excellent temperature stability makes it a highly reliable and efficient choice for many designs.
