Qorvo is now expanding its own SiC portfolio with 1200V SiC power modules! These modules in the E1B package integrate up to 4 SiC FETs in a bridge circuit.
Qorvo’s SiC FETs are based on a SiC JFET and a Si MOSFET in cascode configuration. Detailed information about this innovative approach can be found here.
In the compact E1B form factor of just 33.8mm x 48mm x 12mm (without mounting lugs), Qorvo integrates the four or two SiC FETs in the full/half-bridge modules. The underlying SiC cascode FETs are characterized by very low RDSON values and very low gate charges. The integrated Si MOSFET at the gate simplifies control considerably (VG(th)= 5V typ, 0…15V allowed drive range).
These advantages can be seen in the half-bridge module UHB100SC12E1BC3N due to the very low RDSON of only 9.4mOhm typical.
Another important factor in module technology is heat dissipation. The FETs are thermally connected using silver sintering technology. This enables a thermal resistance of only 0.23°C/W to be realized. Qorvo also combines this with a special “stacked die” technology. The manufacturer achieves an improved power cycling performance by 2x compared to other SiC power modules on the market.
The modules are designed for operation up to a maximum of 150°C TJ. The UHB100SC12E1BC3N delivers up to 100A continuous drain current (TC <85°C) and thus offers the highest current carrying capacity of the family:
