ERZ-VA5V201

ERZ-VA5V201 is a type of device used in circuit protection. It is part of the TVS (Transient Voltage Suppressors) and MOVs (Metal Oxide Varactor) class of components. Both TVS and MOVs help to protect electronic circuits against rapidly changing voltages that can occur from over-voltage, electrostatic discharge (ESD) and over-current.

ERZ-VA5V201 is classed as an overvoltage protection product and is designed to handle repetitive overvoltage and transient surge current. It is a snap-in type device and consists of three layers: the resistive layer, the dielectric layer, and the protective layer. The device has a trigger voltage of 5 V and a maximum peak pulse current of 40 A with a maximum clamping voltage of 16 V.

The basic working principle of ERZ-VA5V201 is simple. When a voltage spike occurs, the signal is shunted to ground and the electrodes on the device conduct current to limit and dampen the excess overvoltage. This process is known as voltage clamping. The device’s dielectric layer and resistive layer acts as a barrier, ensuring the current flows to the device’s electrodes and does not damage the circuit.

The ERZ-VA5V201 is often used in the following applications: as an ESD protection component in USB ports and mobile phone jacks; in power supply systems where a surge suppression device is needed; in automotive electronics; and in military and aerospace electronics. The device is also used in medical instrumentation and industrial automation.

As an overvoltage protection device, the ERZ-VA5V201 has a number of advantages. It is easy to install, very reliable, and capable of effectively protecting circuits from high levels of surge current. It also has a wide operating temperature range from -55°C to +125°C and is resistant to environmental effects; making it well suited to a variety of applications.

Overall, the ERZ-VA5V201 is suitable for a variety of circuit protection needs, and its low cost and ease of installation makes it an attractive option for many design engineers. With its ability to handle repetitive overvoltage and its wide temperature range, it can guarantee reliable protection for circuits.
