The DT12T10E-B with TO-263 TRIACs is a ROHS compliant, Triac-based electronic component designed and manufactured by Doeshare. It features a standard TO-263 package and is compatible with standard soldering methods. It has a low thermal resistance junction to case and high isolation voltage (2500V), making it suitable for high voltage applications. The DT12T10E-B is primarily used for switching, phase control, and AC power control and features high off-state and gate triggered dv/dt capability. Other features include zero volt gate trigger, low on-state voltage drop, and low junction capacitance.
