Diodes - Zener - Arrays: BZB84-C13,215 Application Field and Working Principle

Diodes - Zener - Arrays is an electronic component that provides a low voltage reference, protection circuitry and voltage regulation. The BZB84-C13,215 is a diode array designed for voltage regulation, damping circuits and high-frequency switching operation. It consists of two or more zener-type diodes connected in series together in a single package.

BZB84-C13,215 is commonly used in applications such as Voltage regulators, DC-DC converters, surge suppressors, and current-limiting protection circuits. This diode array operates within a breakdown voltage range of 4.3 - 5.2V, with a power rating of maximum 2.3W and a maximum operating temperature of +150C.

The diode array has four pins with anode (A1), anode (A2), cathode (K1), and cathode (K2). The anodes A1 and A2 are connected to the power supply, while the cathodes K1 and K2 return the energy to the power supply. The diode array works in four distinct modes:

Breakdown Mode: In this mode, when the applied voltage exceeds the breakdown voltage range of the diodes, the diodes conduct current from the anodes to the cathodes, thus allowing the current flow in the circuit.

Repetitive Surge Mode: The array begins conducting current in pulses. This mode is generally used in applications such as motor controllers and PWM controllers.

Static Switch Mode: In this mode, when a positive voltage is applied to anode A1, the diodes become conductive from anode A2 to cathode K2, allowing current flow. When the voltage drops, the diodes become reverse-biased and stop conducting current.

High Voltage Switch Mode: In this mode, when a negative voltage is applied to anode A2, the diodes become reverse-biased and stop conducting current.

The BZB84-C13,215 diode arrayis a cost-effective device for voltage regulation, damping circuits and high-frequency switching application. This diode array comes with its own packaging, allowing it to be easily mounted onto the board. It features excellent electrical characteristics and reliability and is ideal for use in many applications.
