TVS (transient voltage surges) diodes, MOVs (metal oxide varistors) and other varistors are a group of products used to protect sensitive electronic circuits from damaging over-voltage transients. ERZ-V20D681 is one such product within the varistor category. This product is renowned for its superior performance in applications such as deflector protection, ignition control, power supply transient protection, and automotive intracontrol protection.

The ERZ-V20D681 is ideal for a variety of applications due to its state-of-the-art surge protection technology. It is designed to protect sensitive electronic circuits from damaging over-voltage transients at up to TVS 1500W peak pulse power per line and leakage current up to 2Ω @ 20A typical.

The ERZ-V20D681 also features a wide operating temperature range from -40°C to +125°C, making it suitable for use in harsh environments. The device is compliant with UL1449 and is RoHS compliant. The product also offers a high operational reliability, low leakage currents, and low clamping voltages to ensure high levels of safety.

The working principle of the ERZ-V20D681 is simple. The product is designed with an internal junction diode with an external zener diode, both of which are configured to respond to transient pulses. When an over-voltage transient occurs, the junction diode conducts current through the zener diode, creating a leakage path for current to flow. The zener diode restricts the voltage across the zener diode, thereby allowing the surge current to be diverted from the protected circuit, thus preventing damage.

In addition, the product features a clamping mechanism that limits the surge voltage and current pulse width. This is achieved through the use of an additional diode connected in series with the zener diode which helps absorb the surge voltage. Finally, the device will be reset once the surge is gone, allowing normal operation to resume.

A major benefit of the ERZ-V20D681 is that it can be used in a variety of applications to provide superior surge protection. This makes the product an ideal choice for applications such as signal line over-voltage transient protection, high side protection for automotive engines, and power line protection in elevator cabins. The product can also be used in high-performance equipment such as automotive electronics, commercial electronics, and white goods.

In conclusion, the ERZ-V20D681 is an ideal choice for applications that require superior surge protection. It features an innovative surge protection technology that makes it suitable for use in a variety of applications. It also offers a high operational reliability, low leakage currents, and low clamping voltages to ensure safety, making it an ideal solution for protecting sensitive electronic circuits from damaging over-voltage transients.
