TYN812 12A, 800V way thyristor SCR main parameters are: the average value of a voltage, rated average on-state current IT under certain conditions SCR BTA216, 50 Hz sine between the anode cathode can be continuously passed --- the mean half-wave current. 2, the forward blocking voltage peak VPF control plus a trigger signal is not very open SCR, the forward voltage of the anode voltage is not over the guide can, you can repeat added to both ends of the forward peak voltage thyristor. SCR withstand peak forward voltage can not exceed the value of this parameter is given in the manual. SCR triac between the first and second anode anode A1 A2 SCR BTA212, regardless of the applied voltage polarity is forward or reverse, as long as the control electrode G and the first anode A1 is applied between the positive and negative polarity different trigger voltage, you can trigger the conduction low resistance state. In this case A1, A2 between the pressure drop is about 1V. Once a triac is turned on, even if the loss trigger voltage, can keep the conductive state. Only when the first anode A1, A2 second anode current is reduced SCR BTA412Y, less than maintaining the current or A1, A2 when the voltage polarity between change and no trigger voltage, triac was truncated, this time only to re-add trigger voltage before conduction.
