Additional Details

The POZ3AN-1-202N is typically constructed using a zinc oxide (ZnO) based ceramic material. This material exhibits a non-linear voltage-current relationship, allowing the varistor to act as a high resistance device under normal operating conditions, but quickly switch to a low resistance state when a voltage surge occurs. This allows it to divert the surge current away from sensitive components. The specific voltage rating, capacitance, and surge current withstanding capabilities will be detailed in the datasheet for the part. The ‘202N’ portion of the part number likely corresponds to these specifications. It is important to consult the datasheet to ensure that the varistor is suitable for the specific application requirements. These varistors are designed for surface mount applications and are available in various package sizes.
