TVS - Diodes

TVS420 is a series of integrated components that are widely used in the electronics industry for a variety of applications. This series of diodes are highly reliable, due to their exceptional surge protection capabilities and low leakage current. Furthermore, its robustness makes it an ideal choice for applications requiring long-term reliability. Additionally, they are inexpensive and easy to find components, making them a popular choice over other component types.

Application Field of TVS420

TVS420 is most commonly used in the automotive industry. It is commonly used in starter motors, relays, and electric window switches. Additionally, due to their incredible surge protection capabilities, they are also used in high-voltage applications such as electric vehicles, high power supplies, and power line surge protection. Furthermore, they are also used as short-circuit protection, low-voltage detection in batteries, and variable voltage detection for electronic appliances.

Working Principle of TVS420

The working principle of the TVS420 is based on the theory known as the avalanche effect. This effect is when a voltage is applied to a semiconductor junction with a large reverse-biased potential, which causes a breakdown of the potential barriers. When this occurs, current is generated at the junction and is rapidly accelerated to a high level of voltage. The TVS420 can provide effective protection against high voltage and can suppress voltage levels up to 600V.

The TVS420 is designed with a dual-redundant protection scheme. It has two separate active components at the input with active and passive protection. The active component provides a voltage clamp to protect against high input voltage levels, while the passive component blocks high input frequency electromagnetic interference. This dual-redundant protection scheme ensures that the device will operate reliably under harsh conditions.

The TVS420 is an incredibly powerful and reliable component that is commonly used in a variety of applications. Its exceptional surge protection capabilities, low leakage current, and robustness make it an ideal choice for applications requiring long-term reliability. Additionally, its cost-effectiveness and easy availability make it a popular choice over other components.
