Overview
The BT139X-800/L02Q is a four-quadrant TRIAC (Triode for Alternating Current) produced by WeEn Semiconductors. This component is designed to handle medium power switching applications and is capable of operating with loads up to 800V and 16A. The BT139X-800/L02Q is particularly useful in applications requiring the switching of AC loads, as it can operate in all four quadrants, allowing it to switch both positive and negative currents with either a positive or negative gate current.
