Along with the zener diode PN junction temperature change its regulated voltage value can have the corresponding drifting . From the use said its change value is smaller the constant voltage performance is better .

随着 稳压管PN结温度的变化，其稳定 电压值会发生相应的漂移，从使用上来说其变化值越小稳压性能越好。

Zener diodes behave in this way which makes them useful as voltage regulators .

齐纳 击穿二极管就是这种工作方式，在 电压稳压方面非常有用。

In the voltage regulator circuit the zener diode which acts as the voltage datum along with the temperature change its regulated voltage value also can have the corresponding change .

在稳压电路中，作为 电压基准的 稳压二极管，随着温度的变化，其稳定电压值亦会发生相应的变化。

It 's just that a buried zener is even better if you can afford the higher voltage drop .

如果你可以承受更大的 电压跌落的话，一个隐藏 型 的 稳压 管 似乎更好一点。

Therefore the examination of the zener diode voltage drift parameter has the vital significance .

因此， 稳压二极管 电压漂移参数的检测具有重要的意义。

This article narrated several kind of plans of examining high accuracy zener diode parameter emphatically researched the test method of taking high accuracy constant-source as datum current to examine the voltage drift of zener diode .
