The (amplified) current level of the supply must meet or exceed the steady state gate current (I G,steady) required to operate the GA20JT12-247. The power level of the supply can be estimated from the target duty cycle of the particular application. IG,steady is dependent on the anticipated drain current ID through the SJT and the DC current gain hFE, it may be calculated from the following equation. An accurate value of the hFE may be read from Figure 6. 5V SiC SJT TTL Gate Signal D G 5/0V TTL i/p IG,steady S Figure 22: TTL Gate Drive Schematic B: High Speed Driving The SJT is a current controlled transistor which requires a positive gate current for turn-on as well as to remain in on-state. An ideal gate current waveform for ultra-fast switching of the SJT, while maintaining low gate drive losses, is shown in Figure 23 which features a positive current peak during turn-on, a negative current peak during turn-off, and continuous gate current to remain on. Figure 23: An idealized gate current waveform for fast switching of an SJT. An SJT is rapidly switched from its blocking state to on-state, when the necessary gate charge, QG, for turn-on is supplied by a burst of high gate current, IG,on, until the gate-source capacitance, CGS, and gate-drain capacitance, CGD, are fully charged. Jan 2015 http://www.genesicsemi.com/commercial-sic/sic-junction-transistors/ Pg 7 of 11 GA20JT12-247 Ideally, IG,pon should terminate when the drain voltage falls to its on-state value in order to avoid unnecessary drive losses during the steady on-state. In practice, the rise time of the IG,on pulse is affected by the parasitic inductances, Lpar in the device package and drive circuit. A voltage developed across the parasitic inductance in the source path, Ls, can de-bias the gate-source junction, when high drain currents begin to flow through the device. The voltage applied to the gate pin should be maintained high enough, above the VGS,sat (see Figure 7) level to counter these effects. A high negative peak current, -IG,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 satisfactory turn off can be achieved with V GS = 0 V, a negative gate voltage VGS may be used in order to speed up the turn-off transition. Two high-speed drive topologies for the SiC SJTs are presented below. B:1: High Speed, Low Loss Drive with Boost Capacitor, GA03IDDJT30-FR4 The GA20JT12-247 may be driven using a High Speed, Low Loss Drive with Boost Capacitor topology in which multiple voltage levels, a gate resistor, and a gate capacitor are used to provide fast switching current peaks at turn-on and turn-off and a continuous gate current while in on-state. A 3 kV isolated evaluation gate drive board (GA03IDDJT30-FR4) utilizing this topology is commercially available for high and lowside driving, its datasheet provides additional details about this drive topology.

The GA03IDDJT30-FR4 evaluation board comes equipped with two on board gate drive resistors (RG1, RG2) pre-installed for an effective gate resistance3 of RG = 3.75 Ω. It may be necessary for the user to reduce RG1 and RG2 under high drain current conditions for safe operation of the GA20JT12-247. The steady state current supplied to the gate pin of the GA20JT12-247 with on-board RG = 3.75 Ω, is shown in Figure 25. The maximum allowable safe value of RG for the user’s required drain current can be read from Figure 26. For the GA20JT12-247, RG must be reduced for ID ≥ ~13 A for safe operation with the GA03IDDJT30-FR4. For operation at ID ≥ ~13 A, RG may be calculated from the following equation, which contains the DC current gain hFE (Figure 6) and the gatesource saturation voltage VGS,sat (Figure 7).

B:2: High Speed, Low Loss Drive with Boost Inductor A High Speed, Low-Loss Driver with Boost Inductor is also capable of driving the GA20JT12-247 at high-speed. It utilizes a gate drive inductor instead of a capacitor to provide the high-current gate current pulses IG,on and IG,off. During operation, inductor L is charged to a specified I G,on current value then made to discharge IL into the SJT gate pin using logic control of S1, S2, S3, and S4, as shown in Figure 27. After turn on, while the device remains on the necessary steady state gate current IG,steady is supplied from source VCC through RG.

A proportional gate driver relies on instantaneous drain current ID feedback to vary the steady state gate current IG,steady supplied to the GA20JT12-247 C:1: Voltage Controlled Proportional Driver The voltage controlled proportional driver relies on a gate drive IC to detect the GA20JT12-247 drain-source voltage VDS during on-state to sense ID. The gate drive IC will then increase or decrease IG,steady in response to ID. This allows IG,steady, and thus the gate drive power consumption, to be reduced while ID is relatively low or for IG,steady to increase when is ID higher. A high voltage diode connected between the drain and sense protects the IC from high-voltage when the driver and GA20JT12-247 are in off-state. A simplified version of this topology is shown in Figure 29, additional information will be available in the future at http://www.genesicsemi.com/commercial-sic/sic-junction-transistors/ HV Diode Sense Gate Signal Proportional Gate Current Driver Signal D G Output IG,steady SiC SJT S Figure 28: Simplified Voltage Controlled Proportional Driver C:2: Current Controlled Proportional Driver The current controlled proportional driver relies on a low-loss transformer in the drain or source path to provide feedback ID of the GA20JT12247 during on-state to supply IG,steady into the device gate. IG,steady will then increase or decrease in response to ID at a fixed forced current gain which is set be the turns ratio of the transformer, hforce = ID / IG = N2 / N1. GA20JT12-247 is initially tuned-on using a gate current pulse supplied into an RC drive circuit to allow ID current to begin flowing. This topology allows IG,steady, and thus the gate drive power consumption, to be reduced while ID is relatively low or for IG,steady to increase when is ID higher. A simplified version of this topology is shown in Figure 29, additional information will be available in the future at http://www.genesicsemi.com/commercial-sic/sic-junction-transistors/.
