肖特基二极管和普通二极管的区别?

添加时间:2018-01-31

问:肖特基二极管和普通二极管有什么区别呢?

答:肖特基二极管的最大特点是正向压降小,反向恢复时间短肖特基二极管的开启电压低,电荷储存效应小,适于高频工作。同样的电流情况下,它的正向压降要比普通二极管小许多。还具有损耗小、噪声低、检波灵敏度高、稳定可靠等特点,在微波通信和雷达中用于混频、检波、调制、倍频以及超高速开关、低噪声放大等。

 

所以肖特基二极管与普通二极管最明显的区别有以下几点:
1、肖特基二极管正向导通压降比普通二极管低,所以低功耗。
2、肖特基二极管反向恢复时间比普通二极管短,所以工作频率更高。
3、肖特基二极管反向耐压比普通二极管低,一般低于200V。

4、肖特基二极管比普通的二极管通过的电流强。

  5、肖特基二极管比普通二极管的结电容小。
  6、肖特基二极管可以通过高频电流。
 

凌讯生产的肖特基二极管有以下几个特点:

1.采用国际标准芯片制作,性能稳定可靠。

2.封装采用进口环氧树脂,拥有更好的包封和阻燃性能。

3.所用的框架和引脚采用无缝焊接技术锻造而成,材质选用高纯度无氧铜,具有抗弯曲,抗氧化和高导电性能。

4.丝印打码采用的是镭射激光打标,永不褪色,而且高效环保,从一定程度上降低了生产成本。
