Abstract : In this work, static and dynamical chracteristics of SCR(BT51) thyrister have been studied.In relate to static chracteristics, I-V relationship of this device has been illustrated at different temperatures as well as determination of threshold voltage values (Vth) ,studing it's variation as a function of temperature and the result obtaining from this study that the (Vth) is nonlinearly increasing with temperature increasing, this gives the fact that the device senstive to temperature variation.Also, the relationship between both of the conductance and the parameter with anode-cathode voltage variation have been explained.
