Ween Semiconductors Triac TO-220AB 600V 8A - 600V 12A

This Triac from Ween Semiconductors is a planar passivated four-quadrant device housed in a SOT78 (TO-220AB) plastic package, designed for reliable bidirectional switching and phase control in general-purpose applications. With a high blocking voltage capability of 600 V and an on-state RMS current of 8 A, it is well-suited for demanding mains-powered circuits. The less sensitive gate offers improved noise immunity, while the planar passivated construction ensures voltage ruggedness and long-term reliability. Its capability to trigger in all four quadrants makes it extremely versatile for a wide range of control applications.

This through-hole triac is ideal for general-purpose motor controls and load switching, providing a robust solution for AC power regulation. The device features a peak non-repetitive surge current rating of 71 A, making it resilient under transient overload conditions. With a maximum gate trigger voltage of 1 V and a holding current of 20 mA, it offers predictable and efficient performance. The three-pin TO-220AB package allows for straightforward PCB mounting and effective thermal management. Operating at temperatures up to 125 °C, this triac is built for durability in demanding environments. Whether you're designing dimmers, power tools, or industrial controls, this component delivers dependable switching and phase control in a compact, industry-standard form factor.
