For switching high-powered loads from a microcontroller, or for switching AC loads in general, most of us will reach into the parts bin and pull out a generic relay of some sort. Relays are ...

Fig 1. This zero-crossing detector circuit generates the control pulses needed to turn on triacs that require negative pulses for switching. Fig 2. Designers can use ...

The triacs help control ac loads including electric heaters, inductive heating equipment, medium-power motors, and other small appliances. They are rated up to 600 V for mains-powered systems and are ...

Triacs are used to control ac mains loads in home appliances, and commercial and industrial equipment. In the majority of applications, the triac will dissipate sufficient power to make thermal ...

Geneva—STMicroelectronics is calling its latest TRIACs as the first with 10mA gate sensitivity to be specified for operation up to 150°C without derating, enabling low-cost products for heaters, ...
