TVS - Varistors, MOVs

ERZ-U21JP102B is a application field and working principle of TVS - Varistors, MOVs. It is a two-lead varistor designed to protect a circuit from overvoltage transients. It works by diverting energy from a power line and dissipating it as heat, thus preventing it from becoming a destructive surge or spike.

Varistor Basics

Varistors are semiconductor devices that are used to protect against electrical overvoltage transients. They are constructed with a semiconductor material between two metal plates, and when exposed to a specified voltage they will respond by providing a low-resistance path for the energy to be diverted away from the circuit. Varistors are commonly used in electrical systems to protect against power surges, which can cause catastrophic failure of electronic devices.

ERZ-U21JP102B Varistor Working Principle

ERZ-U21JP102B varistors are designed for clamping protection, providing a two-lead structure with ultra-low leakage, and a wide operating range. When exposed to a voltage spike, the metal plates acquire an electric charge and create an electric field that causes the semiconductor material to become conductive. This allows the charge to be diverted away from the circuit, preventing any damage from occurring.

ERZ-U21JP102B Applications

ERZ-U21JP102B varistors are ideal for a variety of applications, including radiation protection, over-voltage protection, and power line protection. They are commonly used in a variety of electronics, including computers, medical devices, industrial motors, and control units. In addition, they can be used in automotive applications, including ignition systems and airbag sensors.

Conclusion

ERZ-U21JP102B varistors are a reliable and cost-effective way to protect circuits from overvoltage transients. Their two-lead structure is perfect for clamping protection, and they have a wide operating range, making them ideal for a variety of applications. With their low leakage and high surge capacity, they are an excellent choice for protecting a variety of electronic devices from electrical surges and power line surges.
