The response to an applied voltage in the forward bias region is controlled by the diode's threshold voltage, which is dependent on the type of material the diode is built with. A silicon diode has an approximate value of V thr = 0.7 V, and a germanium diode has an approximate value of V thr = 0.3 V. Reverse Bias Region

There are many different types of power diodes. Examples include: Basic power diodes consist of a diode built into a chip. Power diode arrays are composed of multiple, discrete, and usually unconnected devices on a single silicon chip. PIN count and number of embedded diodes vary by integrated circuit (IC) package type.
