Working Principles

The BZT52B62-E3-08 comprises a single Zener diode, constructed from a semiconductor junction diode which has been specially designed to operate in the reverse breakdown region. When connected in a circuit in the forward-biased direction, and an applied voltage is greater than the Zener breakdown voltage, a Zener current will flow and a constant voltage drop is provided. The Zener voltage of the diode is determined by the thickness of the depletion layer formed by the junction of the diode, which can be chosen to provide the required voltage regulation.

When connected in a circuit and the applied voltage is lower than the diode’s breakdown voltage, it acts as an open switch, allowing no current to flow. However, if the applied voltage exceeds the Zener voltage, a Zener current flows and maintains a constant voltage drop, limiting the applied voltage to the Zener voltage in the reverse direction to prevent overvoltage. In addition, the device also offers a temperature coefficient of less than 5%, allowing for precise voltage control.
