Diotec has expanded its silicon carbide portfolio with the introduction of the DI075SIC055D7, a 750 V SiC MOSFET aimed at 400 V eFuse applications. The device combines a maximum RDS(on) of 55 mΩ with a D2PAK-7L package and is designed for high-voltage power systems where low conduction losses and fast switching are required.
The company says the MOSFET provides additional voltage margin for 400 V DC bus systems, helping it withstand voltage transients and switching events that can occur during normal operation and fault conditions.
750 V Rating and 55 mΩ RDS(on)
The DI075SIC055D7 has a drain-source breakdown voltage of 750 V and a maximum on-state resistance of 55 mΩ. Other features include low gate charge, low capacitance and low total switching energy.
Recommended gate voltages are 18 V for turn-on and -3 V for turn-off, while the allowable gate-source voltage range is -10 V to +22 V. Maximum drain-source leakage current is specified at 100 µA.
The MOSFET is rated for 214 W power dissipation, supports a peak drain current of up to 132 A and operates over a junction temperature range of -55°C to +175°C.
D2PAK-7L Package
The DI075SIC055D7 is supplied in an industrial D2PAK-7L package with a Kelvin source connection. According to Diotec, the surface-mount package is intended for compact high-voltage power designs while supporting automated assembly.
Diotec lists applications including EV charging systems, solar inverters, telecom power supplies, power factor correction (PFC), switched-mode power supplies (SMPS), DC-DC converters, industrial machinery, motor drives and 400 V eFuse protection circuits.
Samples of the DI075SIC055D7 are available now.
