The SIT9120AC-2D3-25E166.666000Y oscillator functions by using the reverse biased junction effect of the diode. In the oscillator, the series capacitor and the reverse biased diode with its base terminal connected to the inductor make the oscillator circuit. When the power is connected, the capacitor is charged, and then the voltage across the capacitor increases, forcing the diode into forward bias. This results in a current flow, which causes the capacitor to discharge. As the voltage decreases, the diode is reversed biased again, thus creating a cycle that produces periodic pulses.

The frequency of oscillation is determined by an additional components, such as the resistor and inductor. The amplitude of the output signal is then determined by the reverse biased voltage of the diode. The resistor in the circuit prevents the oscillator from entering a nonlinear state, and thus limits the amplitude of the pulse.

Overall, the SIT9120AC-2D3-25E166.666000Y oscillator is a versatile, reliable, and high-performance device that is widely used in a variety of applications. Its small size, superior temperature range, frequency stability, output frequency range, and capability to work with both AC and DC make it an ideal choice for mission-critical applications.
