Diodes are an essential component in any circuit design, used for rectifying and regulating electrical signals. The BAS70-04-TP rectifier array is a special type of high-voltage diode array, designed to handle up to 75 volts in rupture and avalanche, with operating temperatures from -55 ° to +175 ° Celsius. In this article, we’ll take a look at the application fields and working principles of the BAS70-04-TP rectifier array.

The BAS70-04-TP is most commonly used in a range of automotive and industrial applications. Automotive uses typically involve the protection and rectification of high-voltage switching circuits in electronic control units (ECUs), AC/DC converters, battery command modules, and many other related automotive equipment. Industrial uses may involve the protection and rectification of similar circuits, like variable-speed drives, motor control systems, uplink/downlink systems, and many more. The array has also been used as a low-cost option for in-house power supplies in industrial or commercial environments.

When it comes to the working principle of the BAS70-04-TP, its main function is to provide a stable and reliable rectification of low AC input voltage signals. It does this by essentially converting the AC signal into a DC signal using its array of diodes. This involves the diodes allowing the forward current to pass and blocking the reverse current, thus giving the correct current flow for rectification. The array also provides secondary protection by limiting the reverse voltage to safe levels, thus preventing damage to the components.

The array itself consists of four parallel connected diodes, with an additional isolation diode connected in series. The isolation diode is used to protect against any kind of inrush current that may occur during initial power-up. Additionally, due to the multiple junction layers of the diodes within the array, it also provides a high level of circuit isolation, protecting against any stray voltages or currents.

In terms of its electrical specifications, the BAS70-04-TP can handle up to 75 volts in rupture and avalanche, with operating temperatures from -55 ° to +175 ° Celsius. The array also has a low operating current, making it suitable for installations with low-power requirements. It also has an excellent thermal resistance (0.25 K/W), making it ideal for high-temperature applications. Finally, the array is highly reliable and has a MTBF of greater than 1.6 million hours.

Overall, the BAS70-04-TP rectifier array is a reliable, high-performance rectifier suitable for a range of automotive and industrial applications. It is designed for high-voltage, high-temperature operation, and has a low operating current requirement. Its multiple junction layers provide excellent circuit isolation and protection against inrush current, while its excellent thermal resistance makes it highly reliable even in the toughest of conditions.
