Calculation methods for P-channel enhanced VDS and CGS In a P-channel Enhanced Mode FET, VDS represents the voltage between the drain and source, while CGS represents the capacitance between the gate and source. When calculating VDS, it is necessary to consider the working state of the P-Channel Enhanced Mode FET. Generally, the following formula can be used for calculation:

Voltage drop factors of silicon carbide (SiC) diodes The voltage drop of silicon carbide (SiC) diodes refers to the electromotive force difference of SiC diodes. Silicon carbide diode is a semiconductor device with a P-N junction structure that can be used to control current or voltage. The voltage drop of a diode refers to the electromotive force difference between the P-N junction of the diode in the forward conducting state, that is, the forward bias voltage. This is due to the potential difference between the contact surfaces in the diode.

Why does high negative pressure in SiC MOS affect threshold drift The threshold drift of SiC MOSFET is affected by negative pressure because this device has a high leakage current, which reduces the difference between the control terminal voltage and the source terminal voltage, thereby affecting the switching performance of MOSFET. In addition, high negative pressure may also cause MOSFETs to enter rupture mode and trigger other adverse effects.

What are the differences between gallium nitride (GaN) and silicon carbide (SiC)? Gallium nitride (GaN) and silicon carbide (SiC) power transistors, two types of compound semiconductor devices, have emerged as solutions. These devices compete with long-life silicon power lateral diffusion metal oxide semiconductor (LDMOS) MOSFETs and super junction MOSFETs. GaN and SiC devices are similar in some aspects, but there are also significant differences.

5 important techniques for selecting gallium nitride (SiC) MOSFETs To prove that your choice of SiC as the preferred power semiconductor for switch mode design is correct, please consider the following prominent features. Compared to standard or super junction MOSFETs or even IGBTs, SiC devices can operate at higher voltages, frequencies, and temperatures. Most of the power loss of other devices does not exist in SiC devices, so the efficiency of SiC devices can reach over 90% in most applications. Initially, SiC devices were more expensive than other MOSFETs or IGBTs.

What are the advantages of SiC MOSFET over Si MOSFET Compared with Si MOSFETs, SiC MOSFETs have many advantages, including the following:

SiC MOSFET module is a power semiconductor device made of a new material, silicon carbide (SiC), which outperforms mainstream silicon (Si) IGBT and MOSFET devices in high-speed switching performance and high-temperature environments. In industrial equipment applications that require higher rated voltage and larger current capacity, SiC MOSFET modules can meet the application needs, including inverters, converters, and photovoltaic inverters for rail cars, achieving low loss and miniaturization of the system.

What are the differences between SiC SBD and SiC MOSFET? SiC SBD and SiC MOSFET are chips made of polarized silicon carbide material, which have high heat dissipation and conductivity. The difference lies in:

Prospect sharing of silicon carbide (SiC) substrate sheets Silicon carbide (SiC) substrate is one of the key materials for manufacturing SiC devices, which can provide high lattice matching, low defect density, and high-quality surface flatness. With the continuous expansion of the silicon carbide power device market, silicon carbide substrate sheets have also been widely used and are expected to continue to maintain rapid growth in the coming years.

The Development Trend of High Voltage SiC MOSFET The research on high-voltage SiC MOSFETs is gradually deepening, mainly focusing on the design, preparation, and detection of high-voltage SiC MOSFETs. In the past two years, Sic Mosfet has broken through the peak tunneling voltage of 2600V, with crystal surface insulation characteristics as high as 200MV • cm-1, and static performance reaching 500A/1700V for a single chip in a half bridge topology. It can also support constant current and constant voltage regulator operation. In addition, there are SiC Mosfets designed for solid-state dye solar energy to meet the needs of these applications.
