At the moment il1 reaches the positive peak that forces Ds2 to turn on, negative voltage Vc1-Vcf1 is applied to Dataeheet, causing il1 to decrease linearly. STMicroelectronics NV and its subsidiaries ST reserve the right to make changes, corrections, modifications or improvements, to this document, and the products and services described herein at any time, without notice.

Low voltage PNP power transistor. AC line input The triac turn on time per half cycle relates to the power dissipation of the lamp. The dimmer consists of the triac and a few components, see Figure 1.
