Web2 de ago. de 2024 · A diac switches on when its breakdown voltage is exceeded. It remains on until the current through the device drops below the holding current when it turns off and returns to a high resistance state. Its switching and conducting characteristics are mostly symmetrical. In some designs, a diac can be used to trigger an SCR.
WebTo turn on the applicance I set the STM32 output (logic 1 : 3.3V), and I clear this output to turn off the appliance (logic 0; 0V). This ouptput is a push pull type.
