Working Principle

The working principle of the TZQ5258B-GS18 is based on the Zener breakdown effect. The Zener breakdown effect is the electrical breakdown of a diode when an applied voltage is greater than the reverse-biased breakdown voltage. When the reverse-biased diode is electrically stressed and reaches the Zener breakdown voltage, the voltage breaks down, thereby allowing current to flow from cathode to anode. The current through a reverse-biased diode is limited by the breakdown voltage and a resistor in series with it. When the current increases and exceeds a certain value, the diode will get into breakdown state.

The TZQ5258B-GS18 is a reverse-biased diode thus it has a Zener breakdown voltage range of 3.2 to 3.9V. The Zener breakdown voltage of a Zener diode can be easily controlled by the temperature, reverse-biasing and other conditions. The diode works as an ideal source of rectified current, which produces a highly effective rectified voltage at the anode. This rectified voltage is used to control voltage surges or serve as a voltage reduction device.

The working principle of the TZQ5258B-GS18 ensures it can be used in a variety of applications with precision voltage control. Its most common applications are in switching power supplies, as they require precise control of output voltage, as well as in overvoltage protection, voltage regulation and voltage multiplier circuits.
