TVS - Diodes

TVS diode is a device used for protecting a system from overvoltage and electrostatic discharge. It is a type of a Zener diode, which has high breakdown voltage and very low leakage current. The BZA420A,115 device is a TVS diode with an even higher breakdown voltage, up to 1200V, which makes it ideal for use in applications where very high voltage protection is required.

The BZA420A,115 is a silicon TVS diode designed for bidirectional protection from overvoltage transients and has a high surge capability of up to 10V. It has a very low leakage current, so it doesn\'t use up much power. Another benefit of the device is that it has no junction capacitance, which means that it doesn\'t interfere with the signal.

The main application field for the BZA420A,115 is in power supplies, where it can protect against spikes and surges. It can also be used in control systems, to protect against electromagnetic interference (EMI). It is also used in communication systems to protect against overvoltage damage. The device can also be used in HVDC (high voltage direct current) and industrial power applications, to protect the system from overvoltage conditions.

The working principle of the BZA420A,115 is simple. When a damaging voltage transient or overvoltage is applied to the device, it will go into a high-impedance state. This causes the current to be diverted away from the protected components and dissipated in the device. When the voltage transient subsides, the device goes back into a low-impedance state, allowing the normal current to resume.

The BZA420A,115 is an ideal device for applications where a high breakdown voltage and low leakage current is required. Its high surge capability and lack of junction capacitance make it well suited for power supply, EMI, and HVDC protection. It is easy to use and reliable, making it a good choice for designers looking for cost-effective voltage protection for their system.
