Working principle

The working principle of the TZQ5242B-GS18 diode is based on the Zener effect. The Zener effect occurs when a P-N junction is placed in a reverse bias condition. When a voltage greater than the Zener voltage is applied to the diode, a high electric field is produced. Due to excessive electric field, the conduction electrons and the valence electrons released in the junction interface become free, generating a large current. This current results in a constant voltage across the junction, as defined by the Zener voltage. This phenomenon is then used to achieve a constant voltage regulation.

The TZQ5242B-GS18 diode is an ideal Zener diode in terms of design. It has high stability against reverse and forward voltage characteristics, wide temperature range and high-current capability. These features make it an effective and reliable voltage regulator. Thanks to its low forward voltage and low series resistance, the TZQ5242B-GS18 performs better in linear applications.
