;A current stabilizing diode is a component that limits the current flowing through it. Such a semiconductor device in most cases has a housing that resembles a low power diode. Due to the external similarity and the presence of only two leads, components of this class are often referred to in the literature as diode current stabilizers. The internal circuit does not contain diodes, this name was fixed only due to external similarity.
The basis of the circuit is a field-effect transistor with a p-n junction. Gate and source are interconnected. At zero gate-source voltage, the current through the transistor is equal to the initial drain current that flows when the voltage between the drain and the source is greater than the saturation voltage. Therefore, for normal operation of the diode current stabilizer, the voltage applied to the terminals must be greater than a certain value from 1 to 3 volts.
