Q4004L4, TRIAC, TO-220

The Q4004L4 is a silicon bidirectional triode thyristor (TRIAC) designed for general-purpose AC switching and phase control applications. It can handle an RMS on-state current of up to 4A and withstand non-repetitive surge peak on-state currents up to 55A, ensuring reliable performance under demanding conditions. With a gate trigger voltage of 2.5V and a gate trigger current of 25mA, the Q4004L4 is easily triggered, making it suitable for various control applications. Its high blocking voltage of 400V makes it ideal for use in applications such as light dimmers, motor speed controls, and static switching relays. The device is housed in a standard TO-220 isolated package, simplifying mounting and integration into existing designs.
