8 lip 2010 · Triacs have an ~1V drop across it, so multiply that by the current draw to get the simplified power dissipation. 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\$
21 maj 2022 · Building an AC Solid State Relay Using a TRIAC. You can choose to build a single-channel, dual-channel, or multichannel solid-state relay based on your requirements. To build a single-channel solid-state relay, you will need the following components: 220 ohm ¼ watt resistor. 1K ¼ watt resistor. BT136 or similar TRIAC. MOC3021 optocoupler.
6 mar 2017 · • Relay reliability: The load inrush current is managed by the silicon switch, safely thanks to its high current capability. It also increases the relay lifetime, which only drives the steady-state current. Using the triac, the mechanical relay switches when the voltage across it is low, as the triac keeps on conducting, avoiding electrical ...

TRIACs are a subset of thyristors (analogous to a relay in that a small voltage and current can control a much larger voltage and current) and are related to silicon controlled rectifiers (SCRs). TRIACs differ from SCRs in that they allow current flow in both directions, whereas an SCR can only conduct current in a single direction.
