MOSFETs are common field-effect transistors, and the magnitude of their gate-source voltage (Vgs) has an important influence on their operating state. In engineering practice, some applications require the gate-source voltage of MOSFETs to reach relatively high voltages, such as 15V. So, what kind of MOSFET can withstand a gate-source voltage of 15V? This article will discuss this issue and suggest using MOSFETs from VBsemi, a semiconductor company.

Firstly, we need to understand the structure and working principle of MOSFETs. MOSFETs are composed of a source, a drain, and a gate. The electric field between the gate and the drain controls the drain current. Under normal operating conditions, the gate-source voltage of a MOSFET is typically between a few volts and tens of volts, and the maximum gate-source voltage it can withstand depends on its manufacturing process and structure.

Generally, the maximum gate-source voltage of a MOSFET is about twice its operating voltage. For example, if the operating voltage of a MOSFET is 12V, then its maximum gate-source voltage should be around 24V. However, this is just a rough estimate, and the specific value depends on the MOSFET's model and manufacturing process. Therefore, if you need to apply a gate-source voltage of 15V to a MOSFET, you should choose a MOSFET with a maximum gate-source voltage greater than 15V.

There are many brands of MOSFETs available on the market. Here, we recommend using MOSFETs from VBsemi. Established in 2003, VBsemi is a company specializing in the research, development, production, and sales of semiconductor devices such as MOSFETs and IGBTs. VBsemi's products are reliable, stable, and widely used in power supplies, motor control, lighting, and other fields.

VBsemi's MOSFET product line includes N-channel MOSFETs and P-channel MOSFETs, with maximum gate-source voltages ranging from 20V to 600V. Among them, we recommend using VBsemi's N-channel MOSFETs because they have lower on-state resistance and faster switching speed, making them suitable for high-frequency applications. Additionally, N-channel MOSFETs have a wide range of maximum gate-source voltages, making them suitable for most applications.

In addition to the maximum gate-source voltage, other characteristics of MOSFETs should also be considered when choosing them, such as on-state resistance and leakage current. VBsemi MOSFETs have the advantages of low on-state resistance, low leakage current, and high switching speed, meeting the needs of most applications.

In conclusion, if you need to apply a gate-source voltage of 15V to a MOSFET, you should choose a MOSFET with a maximum gate-source voltage greater than 15V. VBsemi's N-channel MOSFETs have the advantages of a wide range of maximum gate-source voltages, low on-state resistance, low leakage current, and fast switching speed, making them an excellent choice. In practical applications, we recommend choosing VBsemi's MOSFET products to ensure the stability and reliability of the system.
