The Q3-Class series Power MOSFETs provide the end-user with a broad range of devices that demonstrate exceptional power switching performance, excellent thermal characteristics, enhanced device ruggedness, and high energy efficiency. Available with drain-to-source voltage ratings of 200V–1000V and drain current ratings of 10A–100A, the Q3-Class series features an optimized combination of low on-state resistance (Rdson) and gate charge (Qg), resulting in a substantial reduction in both the conduction and switching loss of the device.

Power switching capabilities and device ruggedness are further enhanced through the utilization of our proven HiPerFETTM process, yielding a device with a fast intrinsic rectifier which provides for low reverse recovery charge (Qrr) while enhancing the commutating dV/dt ratings (up to 50V/ns) of the device.
