Exploring the Special Features and Benefits of ROHM’s SCT2H12NZ Gate Driver Circuit

The Rohm’s 1700V SiC MOSFET is integrated with unique features, providing unparalleled benefits. Some of the key features and advantages of the SCT2H12NZ gate driver circuit include the following:

• 3.7A Drain Current

One of the standout features of the SCT2H12NZ is its impressive current-handling capacity of 3.7A. This capability ensures it can effectively drive SiC MOSFETs while maintaining stable and responsive operation even in demanding conditions.

• Seamless Compatibility

The SCT2H12NZ’s compatibility with SiC MOSFETs is a game-changer in power electronics. Its precise and responsive gate control ensures efficient switching of SiC MOSFETs, optimising power conversion and minimising switching losses. 

• Low On-Resistance

This driver’s low on-resistance indicates that the gate driver has minimal resistance when in the “on” state. The SCT2H12NZ boasts 1.15 Ω on-resistance, almost eight times smaller, which leads to efficient and low-power operation.

• Total Harmonic Distortion (THD) Reduction

The SCT2H12NZ gate driver circuit addresses the issues of THD–a critical parameter in power electronics, particularly in applications where the quality of the output waveform is essential. High THD can result in increased heat generation, reduced system efficiency, and electromagnetic interference. 

• Fast Switching Speed

Fast switching speeds are crucial for efficiently driving power devices such as MOSFETs or IGBTs. The Rohm next-generation SiC MOSFET provides a fast-switching speed and minimises switching losses.

• Improved Efficiency

The SCT2H12NZ is known to improve up to 6% efficiency by combining with Rohm’s AC-DC converter control IC. The circuit also improves the performance of bespoke converters and other industrial equipment, making it a professional choice for high-efficiency environments and applications. 

• Long Creepage Distance 

The SiC MOSFET from ROHM is designed to provide enough creepage distance–an important safety feature, especially in high-voltage applications. A long creepage distance helps prevent electrical arcing or short circuits, enhancing the circuit’s reliability and safety.

• Simple Driving

Ease of use and simplicity in driving the gate driver circuit can save time and effort during the design and implementation stages.

• Pb-Free Lead Plating 

The MOSFET circuit is incorporated with lead-free materials that are environmentally friendly and comply with RoHS (Restriction of Hazardous Substances) regulations. 

• Precision Pulse Width Modulation (PWM)

The SCT2H12NZ incorporates advanced PWM control techniques, allowing the device precision controls. This, in turn, minimises distortion in the output waveform and reduces THD levels. 

• RoHS Compliant 

The SiC MOSFET driver is RoHS compliant and does not contain hazardous materials like lead, mercury, cadmium, and others–meeting all environmental standards and regulations.

Typical Applications of ROHM 1700V SiC MOSFET

The SCT2H12NZ SiC MOSFET is designed to offer extensive applications for industrial equipment, industrial inverters, general-purpose inverters, solar inverters, robots, manufacturing industries and equipment, and testing devices.
