The FDMS3686S family is a group of power MOSFET arrays. These arrays are ideal for application in high power motor control, DC-DC converter, lighting and other applications that require significant amounts of power to be managed. In this article, we will discuss the applications and working principle of the FDMS3686S family.

The FDMS3686S family consists of two discrete power MOSFETs, each of which features an integrated body-diode. These n-channel, high voltage, high current MOSFETs are designed for applications such as AC adapters and DC-DC converters. The integrated body-diode allows for a low-resistance architecture in applications that require high-side and low-side MOSFETs for simultaneous turn-on/turn-off or for paralleling of two MOSFETs for higher load current. Furthermore, the integrated body-diode also helps reduce switching losses and ensures a faster recovery time from diode conduction.

The FDMS3686S family is suitable for a wide range of applications. It can be used in high power motor controllers, such as motor control units, motor drives and speed controllers. In DC-DC converters, the FDMS3686S family is suitable for high-performance H-bridge designs with pulse-width modulation (PWM). This can be used to regulate output voltages and also create robust power solutions. The FDMS3686S family is also suitable for lighting applications, such as LED lighting and high-brightness LED (HB LED) drivers.

The operating temperature range of the FDMS3686S family is from -40℃ to +150℃, which makes it suitable for a broad variety of industrial applications. The die attach method for the FDMS3686S family is tape and reel and the SOP-7 package provides a excellent thermal performance, which is essential for power applications.

The FDMS3686S operates using the source-to-drain voltage along with the gate-to-source voltage. This is called its operating voltage. When the gate-to-source voltage is low, the source-to-drain voltage must be higher than the operating voltage to turn the MOSFET off. The operating voltage must remain high enough to sustain current flow throughout the MOSFET, otherwise it will start to degrade.

The FDMS3686S also has a threshold voltage, which is the amount of gate-to-source voltage required to turn the FDMS3686S on. The threshold voltage of the FDMS3686S is typically around 1.2V. This means that the MOSFET will turn on when the gate-to-source voltage is equal to or greater than the threshold voltage.

In conclusion, the FDMS3686S family is a group of power MOSFET arrays that is suitable for a wide range of high power applications such as motor control, DC-DC converters and lighting. Its operating voltage and threshold voltage allow for efficient and controlled regulation of current flow through the device. Its operating temperature range and package type further make it an ideal choice for industrial applications.
