Understanding Thermal Dissipation and Design of a Heatsink

WebThe main difference between SCR and TRIAC is that SCR is a unidirectional device, while TRIAC is a bidirectional device. A thyristor is more reliable, while a TRIAC is less reliable. A thyristor requires two heat sinks, while a TRIAC requires only one heat sink. The thyristor controls DC while the TRIAC controls both DC and AC.
