  • Low-Cost Electric Range Control Using a Triac
    eliminates these drawbacks. The PIC10F204, Microchip's 6-pin PICmicro (R) microcontroller (SOT-23 package), is used to implement this solution. The PICmicro gathers user inputs from a potentiometer and controls current to the heating element via a triac. This application note will discuss triac theory, so
  • Gating, Latching, and Holding of SCRs and Triacs (.pdf)
    Gating, latching, and holding currents of thyristors are some of the most important parameters. These parameters and their interrelationship determine whether the SCRs and triacs will function properly in various circuit applications. This application note describes how the SCR and triac parameters
  • Teccor Thyristors used as AC Static Switches and Relays (.pdf)
    Since the SCR and the triac are bistable devices, one of their broad areas of application is in the realm of signal and power switching. This application note describes circuits in which these thyristors are used to perform simple switching functions of a general type that might also be performed
  • Fundamental Characteristics of Thyristors (.pdf)
    , and reliability specifications which their electro-mechanical counterparts cannot fulfill. This application note presents the basic fundamentals of SCR, triac, sidac, and diac thyristors so the user understands how they differ in characteristics and parameters from their electromechanical counterparts
  • Solid-State Relays and I/O
    quickly wear out conventional electromechanical relays. General-purpose SSRs have on/off cycle lifetimes as high as 100,000 actuations. SSRs that can be actuated with conventional CMOS and TTL logic-level voltages are available. SSR failure modes are primarily determined by the triac or SSR switching
  • Electric cooktops with a twist
    tries to move to the coolest place inside the cooktop: the electronic-control area. This area must stay relatively cool (below about 105 C) because it contains critical components such as the capacitor, transformer, and relays or triac. That compares to the roughly 300 C usually present at the heater
