a. Vdsm/Vrsm=Vdrm/Vrrm+200V;
b. Unless otherwise stated, Lgt, Vgt, Ih, Vtm, and Viso are debugging values ??under 25, and other parameters in the table are test values ??under Tvjm;
c. I2t=I2tsmTW/2, where TW: bottom width of sinusoidal half-wave current, at 50HZ frequency, I2t(10ms)=0.005I2tsm(A2S);
d. When used at a current of 60HZ, Itsm(8.3ms)=1.066(10ms),I2t(8.3ms)=0.943I2tsm(10ms)。
