BTB04-600SL is a 4A TRIAC from ST Microelectronics with a rated current of 4A and a voltage rating of 600V. This TRIAC features a high surge current capability and is suitable for applications such as lighting, corded power tools, and industrial.
The BTB04-600SL is a four‑quadrant TRIAC intended for general‑purpose applications that require high surge‑current capability, such as lighting, corded power tools and industrial equipment. It features a gate‑current sensitivity of 10 mA and is supplied in a TO‑220AB package.
The sheet lists key parameters including a 4 A RMS on‑state current, 600 V voltage rating, thermal resistances of 3 °C/W (junction‑to‑case) and 60 °C/W (junction‑to‑ambient), and mechanical dimensions of the TO‑220AB package. Additional data cover surge ratings, dV/dt and dI/dt limits, and ordering information.
