GA20JT12-CAL aug 2014 http://www.genesicsemi.com/high-temperature- sic/high-temperature-sic-bare-die/ pg5 of 7 section v: GA20JT12-CAL gate drive theory of operation the sjt transistor is a current controlled transistor which requires a positive gate curr ent for turn-on as well as to remain i n on-state. an ideal gate current waveform for ultra-fast switching of the sjt, while maintaining low gate drive losses, is shown in figure 11. figure 11: idealized gate current waveform a: gate currents, i g,pk /-i g,pk and voltages during turn-on and turn-off an sjt is rapidly switched from its blocking state to on-state, when the necessary gate charge, q g , for turn-on is supplied by a burst of high gate current, i g,on , until the gate-source capacitance, c gs , and gate-drain capacitance, c gd , are fully charged. , as an example, an i g,pon 3 a is required to achieve a 25 ns v ds fall time for a 800 v switching transition, due to the gate-drain charge, q gd of 77 nc for the GA20JT12-CAL. the i g,pon pulse should ideally terminate, when the drain volt age falls to its on-state value, in order to avoid unnecessary drive losses during the steady on-stat e. in practice, the rise time of the i g,on pulse is affected by the parasitic inductances, l par in the to-247 package and drive circuit. a voltage developed ac ross the parasitic inductance in the source path, l s , can de-bias the gate-source junction, when high drain currents begin to flow through the device. the applied gate voltage should be maintained high enough, above the v gs,on (see figure 7) level to counter these effects. a high negative peak current, -i g,off is recommended at the start of the turn-off transition, in order to rapidly sweep out the injected carriers from the gate, and achieve rapid turn-off. while sati sfactory turn off can be achieved with v gs = 0 v, a negative gate voltage v gs may be used in order to speed up the turn-off transition. b: steady on-state after the device is turned on, i g may be advantageously lowered to i g,steady for reducing unnecessary gate drive losses. the i g,steady is determined by noting the dc current gain, h fe , of the device from figures 5 and 6. the desired i g,steady is determined by the peak device junction temperature t j during operation, drain current i d , dc current gain h fe , and a 50 % safety margin to ensure operating the device in the satu ration region with low on-state voltage drop by the equation: , , 1.5
