Diodes - Rectifiers - Arrays cover a number of devices and components used for rectification and other purposes. Among these devices is the BAS70BRW-7, which is a rectifier array (also known as silicon-controlled rectifier array) that is used to convert alternating current (AC) signals into pulsed direct current (DC) signals. The device consists of four independent silicon-controlled rectifier (SCR) units, each with a dedicated gate terminal, an anode terminal and a cathode terminal. In this article we shall discuss the application field of the BAS70BRW-7, as well as its working principle.

Applications

The BAS70BRW-7 is typically used in the construction of phase-control circuits, where the phase-control circuit works by varying the amount of power delivered to a load by modulating the firing angle. This can be used, for instance, to control the speed of motors, regulate AC power and to produce effects such as stroboscopic light effects. Moreover, the device is useful in situations where AC signal signal processing is required, such as welding, power switching and inductive heating applications.

The device can also be used as a temperature switch, since its on/off switching capability can be used to monitor the temperature of a particular area and switch a load on/off when the temperature reaches a certain level. The device can also be used in a variety of AC power devices, including inverters, UPS, generators and more.

Working principle

The BAS70BRW-7 is formed of four independent SCRs, each with a gate terminal, an anode terminal, and a cathode terminal. A silicon-controlled rectifier is a four-layer solid-state device which consists of a p-type semiconductor layer sandwiched between n-type layers. This p-n-p-n sandwich structure gives the SCR the ability to control current flow in an AC power source once it has been switched on.

When a small current is applied to the Gate terminal of the SCR, it triggers a switching action which causes a larger current to flow through the SCR, which is controlled by the magnitude of the current flowing through the Gate. The SCR can be switched off by reversing the polarity of the Gate current, thus allowing the stored energy to be released in the form of a current.

By using the four independent SCRs contained in the BAS70BRW-7, it is possible to control the power delivered to a load by modulating the firing angle, thus controlling the time for which the SCR is conducting current. The result is a pulsed DC output instead of a steady DC output.

Conclusion

The BAS70BRW-7 is a rectifier array that is commonly used in applications such as phase-control circuits and AC signal processing. The device consists of four independent SCRs, each with a dedicated gate terminal, an anode terminal, and a cathode terminal. By using these SCRs, the device can convert AC signals into pulsed DC signals, and can also be used for temperature switching applications and AC power devices. This is the main application field and working principle of BAS70BRW-7.
