Thyristor drive LED flashing circuit

Published:2011/4/11 2:08:00 Author:Nicole | Keyword: thyristor, LED | From:SeekIC

The oscillator which is composed of unijunction transistor Q1 will produce a series of timing pluse triggering thyristor, and then the thyristor drives red LED. When the flash speed is 12/s, the work current is only 2mA.
