Diodes - Zener - Arrays

The BZB84-B56,215 is a type of diode array manufactured by Vishay Intertechnology that operates in the -6v to 75V range and is rated at 0.5 amperes (A). It is a three terminal device consisting of two diodes that are connected in series, and a common terminal at the negative end.

The two reverse breakdown diodes of the BZB84-B56,215 device have a common cathode. Its operating temperature range is between -55°C and 150°C. Its Vz and Iz values of the device are specified in the following format: ‘BZB84-B56,215: -6V to 75V @ 0.5A’, which means that the device can operate in a voltage range of -6V to 75V, and can handle a current of 0.5A.

Applications

The BZB84-B56,215 can be used in many applications including power supply, EMI noise suppression, AC/DC converters, audio amplifiers, radio receivers, controlled rectifiers, switching regulators, and oscillators. It is widely used in the automotive, telecommunications, and consumer electronics markets.

Working Principle

The BZB84-B56,215 operates on the principle of breakdown voltage, which states that when the applied voltage to a semiconductor device, like a diode, exceeds the rated maximum reverse breakdown voltage, the current begins to conduct in the reversed direction, leading to an avalanche of electrons. This is what is referred to as zener breakdown or zener diode.

The BZB84-B56,215 has a positive breakdown voltage of 75V, a negative breakdown voltage of -6V and a rated current of 0.5A. When the applied voltage is above the positive breakdown voltage (75V), the current will begin to flow in the reversed direction and the two diodes in the device will start conducting simultaneously. Similarly, when the applied voltage is below the negative breakdown voltage (-6V), the two diodes will start to conduct in their normal state.

The BZB84-B56,215 is, therefore, a useful device in the regulation of current in various devices and circuits. It can be used to make a variable voltage regulator, as it can be used to adjust the voltage level of the output according to the applied voltage level.

Conclusion

The BZB84-B56,215 diode array is an effective way to regulate current flow in a variety of devices and circuits. Its low voltage and high current ratings make it suitable for many applications, ranging from EMI noise suppression to audio amplifiers. Its two series connected diodes are capable of providing a regulated voltage output with a wide range of input voltages.
