The ERZ-V20D680 is a transient voltage suppressor, designed for use in various applications. It is made up of two components, an integrated circuit and a voltage diverter. The integrated circuit in the device helps to reduce the voltage differential between the anode and cathode by diverting the current away from the cathode whenever an overload or transient voltage is applied. This prevents damage to the components connected to the circuit. The components of the ERZ-V20D680 include a metal oxide varistor (MOV), a diode, and a capacitor. The MOV helps to absorb any excess energy and reduce the transient voltage and electrical noise. The diode will prevent the current from flowing from the anode to the cathode when excessive voltage is present. Lastly, the capacitor helps to filter out electrical noise and reduce the potential for damage or interference. The ERZ-V20D680 is designed to be used in a variety of applications, including automotive, cellular, industrial, networking, telecom, and more. It can be used as protection against overvoltage and transients in power supplies, monitoring circuits, and other electrical systems. The device can also be used as a filter for electrical noise, and to provide EMC/EMI protection.In terms of features, the ERZ-V20D680 is capable of handling up to 680 volts of transient voltage protection, along with pulse current up to 80 mA. It has an operating temperature range of -40°C to 85°C, and is rated for a continuous operating voltage of 18.3V. The device is designed with a large dielectric absorption ratio, allowing it to absorb energy up to 380 volts. When it comes to the working principle of the ERZ-V20D680, the device works by diverting the excess current away from the cathode whenever an overvoltage or transient voltage is applied. This prevents the components connected to the circuit from being damaged. This is achieved by the device’s metal oxide varistor, diode, and capacitor, all of which are designed to protect the circuit from overvoltage and transients. The varistor helps to absorb any excess energy, while the diode and capacitor help to reduce electrical noise and filter out EMC/EMI interference. Overall, the ERZ-V20D680 is a reliable and effective device designed for use in a variety of applications, offering excellent protection against overvoltage and transients. Its integrated components provide efficient protection against electrical noise, EMI interference, and other external stresses. This makes it ideal for use in a variety of applications, from automotive to networking and telecom.
