What should be noted when selecting a voltage regulator diode?

What is a voltage regulator diode? It utilizes the phenomenon of PN junction reverse breakdown state, where the current can vary over a large range and the voltage is basically not controlled, playing a stabilizing role. So, what problems will you encounter when selecting a voltage regulator diode?

1. Voltage regulation range: In fact, there will be a voltage range to meet everyone's requirements

2. Voltage stabilizing current: Within the range of rated current, voltage stabilizing can be achieved

3. Working frequency of voltage stabilization: Generally, there is an upper limit to the frequency of voltage stabilization

4. Packaging method: You can choose the packaging method that suits you according to your usage situation

The above four points are relatively common selection issues for voltage regulator diode.
