The BTW67 / BTW69 Series is suitable in applications where power handling and power dissipation are critical, such as solid state relays, welding equipment, high power motor control. They offer superior performance in surge current handling capabilities thanks to their clip assembly technology. With their internal ceramic pad, they provide high voltage insulation (2500VRMS), complying with UL standards.
The BTW67 and BTW69 series are high‑power silicon‑controlled rectifiers (SCRs) offered by STMicroelectronics. They are designed for applications requiring robust power handling and dissipation, such as solid‑state relays, welding equipment and high‑power motor control.
The datasheet provides main features, absolute and electrical ratings, thermal resistance data, mechanical dimensions for the RD91 and TOP3 insulated packages, and ordering information including voltage options (600 V, 800 V, 1200 V) and packaging types (tube or bulk).
