The BSD214SN L6327 is a high performance dual N-channel enhancement mode power field effect transistor (FET) designed for applications such as motor control, DC-DC converters, DVD/CD recorders, cellular telephone power amplifiers, etc. It has an extremely fast switching speed and low on-state resistance (Rdson). The device is fabricated using SupreMOS GD-FET Technology, which uses a nitrided oxide-silicon superjunction structure for improved performance.

Application Field

The BSD214SN L6327 is specifically designed for use in DC-DC converters, power switches and motor control applications, where it can act as a power switch switching both AC and DC signals. It is also suitable for other applications such as DC-AC converters and inverters, audio power amplifiers, and power supply circuits.

Working Principle

A field-effect transistor (FET) is a type of transistor that uses an electric field to control the flow of current. The BSD214SN L6327 is a dual N-channel Enhancement-mode FET, meaning that it has two N-type MOSFET (Metal Oxide Semiconductor Field Effect Transistor) chips being operated in parallel. It utilizes the "enhancement" principle, which means that the current flow is controlled by the gate voltage; when the gate voltage is zero, the device is off and when it is greater than 0 V, it is on.

The device has a low on-state resistance (R_{ds_on}), meaning that it has high conduction performance, allowing for fast switching speed. It also has very low static power dissipation and is not prone to shoot-through, making it very suitable for high frequency switching applications.

Conclusion

The BSD214SN L6327 is a high performance dual N-channel enhancement mode power field effect transistor (FET). It is specifically designed for use in DC-DC converters, power switches and motor control applications, where it can act as a power switch switching both AC and DC signals. The device has a low on-state resistance (R_{ds_on}) and fast switching speed, making it very suitable for high frequency switching applications.
