The BAS40W-06-7 is an array offered by the Diode and Rectifier Division of ON Semiconductor. It is part of their BAS40F family of rectifiers, which are designed for automotive applications, including blower motors, starter motors, and lighting. It has a breakdown voltage of 40V and a forward current rating of 0.7A.

The BAS40W-06-7 array has seven Schottky diodes in one single package, with a common cathode configuration. This saves board space and simplifies circuit design. The array dissipates a maximum power of 0.5 watts at room temperature, and its resistance between Pins 2 and 3 is less than 1Ω. It is available in both surface-mount and through-hole packages.

The basic working principle of a Schottky diode is based on the junction between a metal and a semiconductor. When two dissimilar materials are placed in contact with each other, a type of electrical barrier is formed. Electrons cannot cross this junction without the presence of an external voltage source. This barrier prevents the current from flowing in reverse direction, making the Schottky diode a useful rectifier.

The BAS40W-06-7 rectifier array combines this basic principle with seven diodes in one package. This produces a greater current carrying capacity within a limited space. The Schottky barrier also blocks the flow of reverse current, reducing the power dissipated. Additionally, the package of the BAS40W-06-7 is designed for automotive applications, so it can withstand extreme temperatures and a diverse range of EMI/RFI fields.

Overall, the BAS40W-06-7 rectifier array is an ideal choice for automotive electronics, due to its combination of power handling capacity and low-power dissipation. It is also reliable, as Schottky diodes are known to have a greater reliability than other rectifier types. The package is designed for high-temperature environments, making it a suitable solution for applications such as blower motors and starter motors. Finally, its size helps to simplify circuit design and occupy minimum board space.
