Diodes are an integral component in modern electronics and play a critical role in many electrical power conversion applications. Arrays of diodes such as the BAS16VY/ZLZ provide improved flexibility and performance when compared to using a single diode. In this article, we will discuss the application field and working principle of the BAS16VY/ZLZ diode array.

As the prefix “BAS” implies, the BAS16VY/ZLZ is a surface-mount array of bipolar schottky diodes. This specific array includes 16 individual diodes in an outwardly facing arrangement. The “VY” industrial grade type is available in a hermetic package, allowing greater versatility in usage and environments. Additionally, the “ZLZ” Automotive grade type is also available, allowing the diode arrays to be used in automotive and other harsh environments.

The primary application of this diode array is for the protection of components from surges or other transient voltages. The individual diodes are connected to form a protective bridge and are optimized to protect against input and output voltage fluctuation. As an example, the BAS16VY/ZLZ can be used in a motor control circuit to prevent over- or under-voltage transients and spikes from damaging circuitry. Alternatively, the diode array can be used to handle high switching currents that would otherwise cause a single diode to fail.

In terms of the working principle of the diode array, each diode is designed to limit current in one direction. When a voltage is applied to the array, the individual diodes become forward-biased, allowing current to flow through unsaturated paths. When the voltage is reversed, the individual diodes become reversed-biased, blocking any additional current from flowing and protecting the circuitry from damage. This prevents current from flowing beyond the diode’s threshold and is referred to as “clamping”, enabling the array to safely dissipate high-amplitude transient energies.

In conclusion, the BAS16VY/ZLZ array is a special type of diode array designed for handling high-current pulses and spikes. The individual diodes are arranged in a specific outwardly facing array with optimized forward- and reverse-biasing characteristics. This allows the array to protect sensitive electronics and components from transient voltage surges.
