The 1N4742A is a voltage regulator diode, with low voltage regulator diodes in hermetically sealed SOD 66 (DO-41) packages. The series consists of 22 types with nominal working voltages from 3.3 to 24 V. The voltage regulation value of 1N4742A is 12V, the voltage regulation range is 5%, and the IFSM surge current can withstand 10A.
The voltage stabilizing diode is a diode that uses the reverse breakdown state of the PN junction, and its current can vary in a large range while the voltage is basically unchanged. This diode is a semiconductor device that has a very high resistance up to the critical reverse breakdown voltage.
At this critical breakdown point, the reverse resistance is reduced to a very small value. In this low resistance region, the current increases while the voltage remains constant. Zener diodes are divided according to the breakdown voltage because of this characteristic, Zener tubes are mainly used as regulators or voltage reference components. Zener diodes can be connected in series for use at higher voltages, and higher stable voltages can be obtained by connecting them in series.
