Abstract
PURPOSE:To improve the stability of rejecting pulsive noise by connecting a Zener diode in series with a diode in opposite polarity. CONSTITUTION:1st and 2nd diodes 4, 5 are connected in series with 1st and 2nd Zener diodes 8, 9 respectively in opposite polarity. This connection signifies concretely that the cathode of the diode is connected in series with the cathode of the Zener diode. Both the temperature characteristics of the diode and the Zener diode are canceled together and a breakdown voltage independently of the temperature change is obtained. Thus, the stability of rejecting pulse noise is improved.
