Description: This triac is designed primarily for ac power switching. The gate sensitivity of these triacs permits the use of economical transistorized or integrated circuit control circuits, and it ...

[Daniel] knew how the TRIAC functioned in the circuit and also knew that a standard TRIAC of sufficient specifications could be used as a replacement even if it didn’t have the correct form ...

Includes: Low Noise Infinitely Variable Resistor as Output Element Resistance Is Inversely Proportional to Input Drive Current Applications: Audio Limiting and Compression Automatic Gain Control ...

The PIC is powered by a large capacitor while the triac is conducting, preventing it from resetting until the circuit can start stealing power again. Pretty clever stuff, and a nice PCB design to ...
