The T435-600T is a thyristor TRIAC manufactured by STMicroelectronics. It is a 600V, 31A device with a 3-Pin (3+Tab) TO-220AB tube construction. The thyristor TRIAC is used for controlling and switching, AC power in various electrical circuits. This device is suitable for general purpose, fast time-delay triggering, as well as phase control applications such as inductive loads, hotwater boilers and air conditioning systems. The 3-pin construction is composed of an Anode (Pin1), Gate (Pin2) and Cathode (Pin3+Tab) connection. The device features a blocking voltage of 600V, minimum operating intermittent temperature of -25°C and a maximum of 85°C.
