• BZB84-B18,215 Diodes - Zener - Arrays:

The BZB84-B18,215 is a high power thick film Zener array from Diodes Incorporated that provides very low voltage regulation in high voltage applications. This device is specially designed for industrial use in applications that require higher performance, such as solar and battery charger systems, AC/DC converters, and AC/AC converters. This device is particularly suitable for use in automotive and telecom applications. The BZB84-B18,215 provides excellent breakdown characteristics, low capacitance and leakage resistance, and is designed with a low profile and high power dissipation capability.

The BZB84-B18,215 Zener array consists of four through hole 6.8V Zener diodes that are connected in parallel or series to form a Zener array in either a positive or negative voltage configuration. The overall breakdown voltage is 18.2V, and each diode can provide a breakdown voltage of 6.8V between the pins of each diode. The device also has a high power dissipation rating of 17W. This allows for more efficient operation as well as longer lifetime of the device.

The working principle of the BZB84-B18,215 Zener array is based on the principle of Zener breakdown. Zener breakdown occurs when the Zener diode is subjected to a reverse bias greater than its breakdown voltage, typically 6.8V for this series of diodes. In this scenario, the electric field across the diode increases until its breakdown voltage is reached, leading to a dramatic rise in conduction current through the diode, which then limits the voltage applied a the terminals of the diode. This voltage regulation is known as Zener breakdown. This device can be used in a variety of applications, including:

• Solar and battery charger systems: The BZB84-B18,215 can be used to regulate the charging voltage of solar cells and batteries, ensuring that the charging voltage is constant no matter the input voltage. This provides improved reliability when charging.
• AC/DC converters: The BZB84-B18,215 can be used in AC/DC converters to regulate the output voltage, providing more consistent and reliable operation of the converter. This can also improve efficiency and reduce power consumption.
• AC/AC converters: The BZB84-B18,215 can be used in AC/AC converters to regulate the output voltage, providing improved efficiency and reliability when compared to traditional AC/AC converters.
• Automotive applications: The BZB84-B18,215 can be used in a variety of automotive applications, such as car stereo systems, car alarms, and other automotive electronics.
• Telecom applications: The BZB84-B18,215 can be used in telecom applications such as cell phones, modems, and base station radio equipment.

The BZB84-B18,215 series of Zener arrays from Diodes Incorporated provide a high performance solution for applications requiring very high voltage regulation. This device is particularly suitable for automotive and telecom applications, and can be used to improve the efficiency, reliability, and power consumption of solar and battery chargers, AC/DC converters, and AC/AC converters.
