Q4004L3, Sensitive Gate TRIAC, TO-220

The Q4004L3 is a silicon bidirectional triode thyristor (TRIAC) designed for general-purpose AC switching and phase control applications. With a sensitive gate triggering requirement of a maximum of 10 mA, this TRIAC can be easily controlled by low-power gate drive circuits, making it ideal for interfacing with microcontrollers and other logic devices. The device supports an RMS on-state current of up to 4 A and can withstand non-repetitive surge peak on-state currents up to 55 A, ensuring reliable performance under demanding conditions. The isolated TO-220 package, rated at 2500 V_RMS, enhances safety and simplifies thermal management, making the Q4004L3 suitable for various applications, including motor speed controls, light dimmers, and static switching relays.
