STMicroelectronics Surface Mount 3-Pin TRIAC 800 V Rated Average On-State Current 4A TO-252 Package T405-800B-TR

STMicroelectronics T405-800B-TR is a surface-mounted TRIAC semiconductor device featuring a 3-pin TO-252 package designed for AC power control in various industrial and electronic applications.

With a maximum repetitive peak reverse voltage (VDRM) of 800 V and a rated average on-state current of 4 A, it is suitable for moderate power switching tasks. The TRIAC offers a low gate trigger voltage of 1.3 V and a maximum gate trigger current of 5 mA, facilitating sensitive and efficient triggering with minimal control power.

Its surge current rating of 31 A provides robustness against transient inrush currents, making it reliable in switching inductive loads. Operating temperature ranges from -40°C minimum to 150°C maximum, allowing deployment in harsh environments.

The device is packaged in a compact TO-252 format with physical dimensions of 6.73 mm in length and 2.4 mm in height, suitable for automated PCB assembly methods.

Additional electrical characteristics include a maximum holding current of 10 mA, a peak on-state voltage of 1.56 V, and a repetitive peak off-state current of 1 mA, enabling efficient power management and minimal leakage current.
