Relays, on the other hand, have milliVolts of drop, so they don't have nearly the same losses. Triacs which can handle higher current are typically smaller than a smaller triac with heatsink, so you could look there too. \$\endgroup\$ huben k2

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. WebDec 3, 2024 · If the heat sink has a thermal resistance of 0.5°C/W, then the total should be 1.5°C/W. 125°C * ( [1.5°C/W] / [2.4°C/W]) = ~78°C. So, at peak heat generation, using this …

WebJul 7, 2011 · 1. Jul 7, 2011. #1. Hi, I would like to compute the heat dissipation of a thyristor which is used in Soft-Starters. As far as I know, heat dissipation in thyristors is composed of the two terms, P=V.I (av)+R.I (av)^2. To understand each term of this equation, I am looking for some references in which there is a good description for heat ... Webpower dissipation for a sanity check in your design. The high thermal resistance of the plastic packaging ensures that most of the heat travels from the exposed copper pad to the PCB, which usually has a much lower thermal resistance. A heat sink can be added to either the top of the package or directly beneath the
