Pan Overseas Zinc Oxide Varistors PVR - ZINC OXIDE VARISTORS Introduction Zinc Oxide Varistor is a non-linear resistance device, whose voltage and current relationship vary according to the Law of Powers. When high Voltage transients or surges produced by induced lightning, switching or electrical noise, the varistor will switch from the rest stage to the protective stage. It is extremely high resistance value will change to very low and causes short circuit, allows large currents to go through. Thus the high voltage transients or surges can be suppressed to a safe level. This non-linear exponent characteristic with board application range is designed to protect various kinds of electronic devices and semiconductor elements. Features ¡¯ ¡¯ ¡¯ ¡¯ ¡¯ Low leakage current. Excellent voltage ratio. Fast respond to the rapidly rising surge voltage. High performance in clamping voltage characteristics. High performance in surge current withstanding capability. Applications ¡¯ ¡¯ ¡¯ ¡¯ ¡¯ Transistor, diode, IC, Thyristor, and triac semiconductor protection. Surge protection in consumer electronics. Surge protection in industrial electronics. Surge protection in communication, measuring, and controller electronics. Surge protection in home electronic appliances and gas/petroleum appliances.
