Additional Details

The 12TTS08STRLPBF SCR features a repetitive peak off-state voltage (VDRM) and repetitive peak reverse voltage (VRRM) of 800V. Its average on-state current (IT(AV)) is 12A. The gate trigger current (IGT) is typically low, making it easy to drive with standard logic circuits. It has a standard recovery time, meaning it is suitable for applications where fast switching is not a primary requirement. The SCR is housed in a TO-251 (IPAK) package suitable for surface mounting. Proper heatsinking is recommended to ensure reliable operation at high currents. Vishay SCRs are known for their robustness and reliability in industrial applications. The device is designed to provide stable and predictable performance in a variety of power control circuits.
