BAV70SRAZ Application Field and Working Principle

The BAV70SRAZ is a low-capacitance (1. 2pF) diode/resistor arrays. They can be used to protect sensitive analog and digital circuits from transient electrical or ESD direct or indirect destruction. BAV70SRAZ has single gate technology, a package that permits its use directly on the circuit board. It consists of two diodes and four resistors that are connected to each other in parallel and placed inside a SO-8SMT package.

Application Field

The BAV70SRAZ diode/resistor arrays are commonly used in many applications. The most common application is protection from overvoltage transients. It is commonly seen in automotive and consumer applications, such as power conversion, motor control, car audio and in-vehicle infotainment, to name a few. It can also be used in medical applications such as medical device or implantable electronic circuits.

Apart from these, it can also be used in other applications such as RF systems and ultra-wideband systems, power switching, consumer electronics and wireless communication systems. In addition, this diode/resistor arrays can also be used in industrial applications such as robotics, industrial controllers, etc.

Working Principle

The BAV70SRAZ diode/resistor arrays provide overvoltage protection by using the principle of transient limitation. When the input voltage exceeds a certain threshold, the resistors come into play, limiting the current to a safe level and protecting the device. This protection is also known as a Transient Voltage Suppression (TVS) diode/resistor array.

When the input voltage exceeds a certain threshold, the resistors limit the current to a safe level, preventing the high current from damaging the device. The diode/resistor array also provides a fast response time and prevents high voltage transients from reaching the device. Furthermore, the BAV70SRAZ can withstand ESD discharges up to 16kV, which makes them ideal for use in high-voltage protection applications.

Conclusion

The BAV70SRAZ diode/resistor arrays are a great solution for protecting sensitive analog and digital circuits from ESD and transient electrical destruction. With their single gate technology and package design, these diodes/resistor arrays offer fast response time and can handle up to 16kV ESD discharges. They are most commonly used in automotive, consumer electronics and industrial applications but can also be used in other applications.
