TechnologiesThe MCR100G-6-AC-AB3-R is a RoHS-compliant one-way thyristor, manufactured by Unisonic Technologies, with a 400V SOT-89 (SOT-89-3) package. This device is a TRIAC (thyristor gate turn-off controller) that can be used to regulate power switching and dimming applications. It is designed to provide system protection from overcurrents, short-circuit events, and inductive and capacitive loads. The MCR100G-6-AC-AB3-R features a low threshold voltage, high blocking voltage, and has a low on-voltage drop. Additionally, it has a high surge capability with fast switching times, and operates within a wide temperature range of -40°C to +125°C.
