Diodes are used as both rectifier and switch components in a wide variety of circuit applications. They are also used as clamping mechanisms and transient protection devices. Arrays are integrated circuits or monolithic modules composed of individual diodes connected in a pre-determined configuration. Depending on the required application, the discrete diodes can be arranged in one or more series strings, shunted with a matching diode for forward or reverse rectification, and/or in parallel arrangements. The APTDF400AA60G series is a diode array designed for a variety of applications which require reverse rectification.

It is a component built on a ceramic substrate with low inductance and can handle extremely high currents up to 400A. The APTDF400AA60G series consists of a rectifier chain of four 200A Schottky diodes in a single package. This primary chain is supplemented with a diode string module using a single doulbe sided diode in plastic package. This enhanced module increases the conduction current capabilities to further improve forward rectification performance.

The APTDF400AA60G diode array is designed for use in a wide range of applications where high currents are encountered. Examples include power supply regulation and regeneration, DC/DC converters, high power audio systems, motor control circuits and photovoltaic power supply applications. The combination of high-current rectification capability with low-inductance design make it suitable for these types of applications.

The high-performance Schottky diodes used in the APTDF400AA60G array are extremely reliable and are rated for operation over a temperature range of -55 to 175 degrees C. The ceramic package is highly thermally conductive, which helps to reduce power dissipation and ensure reliability during high current operations. The plastic package also contributes to low thermal resistance, which further improves the power handling capabilities of the APTDF400AA60G.

The operating principle of the APTDF400AA60G diode array is simple. The primary chain of four Schottky diodes is wired in series and operates as a bridge rectifier. This arrangement allows a single polarity of current flow in either direction. The double-sided diode in the parallel module then ensures that any current remaining at the output is blocked from reaching the input. With this type of circuit, both rectification and current blocking can be accomplished with a single device.

In summary, the APTDF400AA60G diode array is a high-performance, high-current rectification device tailored for a variety of applications. Its compact design and low inductance make it suitable for even the most demanding requirements. Its operating principle is simple and provides convenient polarity reversal and current blocking with a minimal number of components.
