Working Principle of BZD27B120P-E3-18

The BZD27B120P-E3-18 functions using the Zener breakdown process. It is a Zener diode made out of gallium nitride and is capable of handling up to 120 volts. The Zener breakdown process is a type of reverse breakdown process in which a small voltage is applied in the forward direction and its junction breaks down, thereby creating a high reverse-current flow. As a result, a wide range of peak currents can be handled with this diode.

The voltage across the diode is limited by the Zener breakdown process, which occurs when the electric field present within the depletion region is greater than a certain critical value. This critical voltage is known as the Zener voltage, and when the junction breakdown voltage is exceeded, the diode begins to conduct in the reverse direction, creating a sudden surge of current.

Once the breakdown voltage is established, this diode is able to function as a voltage regulator and protect the circuit from an over-voltage condition. The Zener breakdown process also helps to protect the circuit when the voltage is too low, as the diode will pass current until the voltage is above the Zener voltage.

The BZD27B120P-E3-18 is also capable of providing reverse over-voltage protection as it will absorb any excessive reverse voltage. It can also provide reverse current limitation, reverse voltage regulation, and voltage clamping. This diode is highly reliable and can protect a variety of circuits in various applications.
