TVS diodes (transient voltage suppressors) are an important class of electronic components that work by limiting the electrical current passing through the device by acting as a reverse breakdown device. This ensures that the voltage across the diode is not exceeded and protects the device from voltage transients. BZA868AVL is one such device used to provide protection from overvoltage situations.

Generally, the BZA868AVL is a bi-directional TVS diode designed for use in automotive, industrial, and telecommunications applications. This device is capable of supporting a maximum of 115V working voltage and is available in two packages –DPAK and SOT-23. The device has an exponential clamping voltage with a 3.9V break-over voltage and a maximum clamping voltage of 19.5V.

The primary application of the BZA868AVL is to provide transient voltage protection for power lines and control lines in automotive applications. The device is commonly used in a voltage division circuit, with a current flowing through two series connected resistors. It then clamps the device’s outputs to a voltage level that is below the device’s rated clamping voltage.

The BZA868AVL works by utilizing avalanche breakdown, which is an abrupt increase in the voltage level across the device. When the voltage reaches a certain level, the diode undergoes a type of breakdown which causes the current to increase rapidly. This sudden increase in the current causes the diode to reach its clamping voltage and start diverting the current in the circuit away from the device. This ensures that the voltage does not exceed the breakdown voltage of the component and thus protecting it from damage due to transient voltages.

The device can be used in a variety of applications such as motor control, switch mode power supplies, telecommunications equipment and automotive systems. The device is commonly used in open-loop motor control applications where it protects the power line from transients. The device also acts as an active protection against reverse voltages, which can damage the device.

The BZA868AVL is designed to provide a wide range of protection solutions for automotive, industrial and telecommunications applications. This device is available in two packages to suit different industrial application requirements, and provides reliable protection against transient voltages. The device works through avalanche breakdown and clamps the voltage to protect the circuit from overvoltage transients.
