TTS-200 Series Temperature-Control Thyristor Basic Application Circuit

Published:2011/5/21 20:25:00 Author:Robert | Keyword: Temperature-Control, Thyristor, Application | From:SeekIC

The temperature-control thyristor basic application circuit is shown in the picture below. RcA is the resistance to control the switch temperature. With different value of RcA it can get different switch temperature. The VD is working voltage. When the temperature is lower than the switch temperature, the temperature-control thyristor is disconnected and the Vo port outputs low voltage level. When the temperature is equal or higher than the switch temperature, the temperature-control thyristor is connected and Vo port outputs high voltage level. It should note that, the working voltage VD also has relations with switch temperature. To assure the stability of the switch temperature, VD should be taken measures of regulating voltage. C is a capacitor to prevent the disturbance.
