What is Drain Source Voltage of FET ?

The drain-source voltage (Vds) of a Field-Effect Transistor (FET) is the voltage difference between the drain terminal (D) and the source terminal (S) of the transistor. It is a key parameter that characterizes the FET's operating conditions and is crucial for understanding and designing FET-based circuits. The V_DS voltage is used to control the FET's operation in different modes, and it can significantly affect the behavior of the transistor. The relationship between V_DS and the drain current (I_d) is essential to determine how the FET functions in various applications.

How to Calculate Drain Source Voltage of FET?

Drain Source Voltage of FET calculator uses Drain Source Voltage FET = Supply Voltage at Drain FET-Drain Current FET*(Drain Resistance FET+Source Resistance FET) to calculate the Drain Source Voltage FET, Drain Source Voltage of FET, the higher the drain-source voltage, the more current will flow through the FET. However, there is a limit to how much current the FET can conduct, which is determined by the pinch-off voltage. The pinch-off voltage is the voltage at which the depletion regions of the gate-junctions meet and pinch off the channel, preventing further current flow. Once the pinch-off voltage is reached, the drain current in a FET becomes relatively constant, even as the drain-to-source voltage is increased. Drain Source Voltage FET is denoted by V_ds(fet) symbol.
