TVS - Diodes - NSQA12VAW5T2G Application Field and Working Principle

TVS - Diodes are used to protect electric devices from high voltage and current transients caused by lightning, industrial power supplies, and even some vehicles, among others. The NSQA12VAW5T2G (Tvs - Diodes) is a transient voltage suppressor (TVS) diode specially designed to provide overvoltage protection in applications that require the highest level of safety and reliability. It offers high clamping voltage, low leakage current, and fast switching time – all features necessary for effective transient protection.

Applications

The NSQA12VAW5T2G is intended for use in applications such as AC power interference filtering, automotive electronic control modules, and other consumer electronics. Additionally, the surge suppression offered by the diode is suitable for use in industrial, lighting, and metering applications, as long as the reverse breakdown voltage and power limits are not exceeded.

Principle

The NSQA12VAW5T2G is a type of Zener diode, which works by allowing current to flow in only one direction, limiting the voltage to the applied breakdown voltage. When a transient exceeds the breakdown voltage level, the diode rapidly increases the voltage across its terminals, thereby limiting the current to a safe level. This limits the severity of a transient event, protecting the component from malfunctions or destruction.The NSQA12VAW5T2G has an extremely reliable breakdown voltage of 12V, allowing it to provide effective protection from high voltage transients up to 10,500V, while still offering excellent surge protection. This diode employs an integrated low inductance design to ensure fast clamping and high surge performance. The low leakage current (<2uA) of the NSQA12VAW5T2G ensures minimal current drain on the device being protected, and its fast response time (<0.5us) provides fast transient response.

Conclusion

The NSQA12VAW5T2G Tvs - Diodes are ideal for a wide range of applications that require fast response, high reliability, and effective transient suppression. Its integrated design, high clamping voltage, low leakage current, and fast switching time make it well suited for AC power interference filtering, automotive ECMs, and other consumer electronics. It is an ideal choice for applications where the highest levels of safety and reliability are required.
