14. Characteristics
14-1. Rated current and heat value
By conducting current to the thyristor, voltage (0.9 － 1.3 V) is gererated between terninals. Voltage between terminals and accumulation of current (W)
turn into Joule heat, resulting in rise in temperature of the thyristor device. Take radiation and ventilation into account.

Rated current of the device assumes an environment where ambient temperature does not rise above 55°C. If ambient temperature exceeds
50°C, reduce load current as shown in the following figure.
