Shenzhen Mingjiada Electronics Co., Ltd. — Long-term supplier of Onsemi UJ4C075023 750V silicon carbide (SiC) EliteSiC Cascode JFETs, designed for high-voltage, high-efficiency power conversion applications such as photovoltaic inverters, energy storage systems, electric vehicle charging, server power supplies, UPS systems and industrial power supplies. We provide genuine products, quotation enquiries and supply support. Specific stock levels, prices, batch numbers and lead times are subject to Mingjiada’s confirmed quotation.

I. Product Positioning
The ON Semiconductor UJ4C075023 belongs to the EliteSiC Cascode JFET series. It utilises a common-source, common-gate (cascode) structure comprising a silicon carbide (SiC) JFET and a low-voltage silicon MOSFET, combining the high voltage rating and low loss advantages of SiC devices with gate drive characteristics similar to those of silicon MOSFETs. This device has a typical breakdown voltage of 750 V and an on-resistance in the 23 mΩ range, making it suitable for high-voltage power supply designs with stringent requirements for efficiency, power density and reliability.
Compared to traditional SiC MOSFETs, the key feature of the Cascode JFET is its normally-off operating mode, whilst its gate drive characteristics are closer to those of silicon MOSFETs, helping to lower the barriers to drive circuit design.

IV. Why Focus on Cascode JFETs
In high-voltage power supply design, SiC devices offer lower switching losses and the potential for higher switching frequencies. The UJ4C075023 utilises a Cascode JFET structure, with its normally-off characteristics facilitating safe system design; its gate drive method is similar to that of silicon MOSFETs, reducing the cost of adapting drive solutions. For designs transitioning from silicon-based power devices to SiC, the UJ4C075023 serves as one of the high-efficiency switching device options in the 750V class.

In power conversion systems such as photovoltaic inverters, on-board charging, server power supplies, industrial PFC and high-frequency DC-DC converters, silicon carbide power devices are central to the upgrade of high-voltage, high-frequency power supplies. Thanks to its comprehensive advantages—including standard drive compatibility, low on-state losses, excellent reverse recovery and a range of package options—the ON Semiconductor UJ4C075023 stands out as a cost-effective choice for the 750V power platform.
