The Z0110MA 1AA2 from STMicroelectronics is a Standard 1 A Triac that is suitable for general-purpose AC switching applications. It has a break-over voltage of 600 V and a break-over current of less than 8.5 A. This thyristor has a gate trigger voltage of up to 1.3 V and a gate trigger current of 25 mA. It has an average gate power dissipation of 5 W, a peak gate current of 1 A, and a junction-to-lead thermal resistance of 60oC/W. This triac is designed with different gate current sensitivities, allowing optimized performance when driven directly through a microcontroller. It is available in a through-hole package that measures 17.1 x 4.7 mm and is ideal for home appliances (electrovalve, pump, door lock, small lamp control) and fan speed controllers.
