A: Static TTL Logic Driving
The GA20JT12-247 may be driven using direct (5 V) TTL logic after current amplification. 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.

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.

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.

Figure 24: Topology of the GA03IDDJT30-FR4 Two Voltage Source gate driver.
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. Please refer to the article
“A current-source concept for fast and efficient driving of silicon carbide transistors” by Dr. Jacek Rąbkowski for additional information on this
driving topology.4

GA20JT12-247
C: Proportional Gate Current Driving
For applications in which the GA20JT12-247 will operate over a wide range of drain current conditions, it may be beneficial to drive the device
using a proportional gate drive topology to optimize gate drive power consumption. 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/

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/.
