The rating is reduced (Fig. 2) by a factor of 0.81 due to the elevated temperature, but it is enhanced by 2X (Fig. 1) due to the air flow. Hence the DC output current is 0.81 x 2, or 1.6 times the 25°C air rating. Forward Pulse Current vs. Duration Multiple Surge Current vs. Duration oe = [ sauare ruse! TTT 1] ae wns TP yl t 7
