缩短HER整流二极管反向恢复时间的实验研究

Research on Shortening the trr Time of HER Diode

采用扩铂工艺制造二极管能够有效地减小开关二极管的反向恢复时间，提高其开关速度。通过实验数据分析，确定了最佳铂扩散温度，提高了ＨＥＲ整流二极管管芯的成品率。

Using the technology of Pt diffusion to produce diodes can shorten the reverse recovery time and increase the velocity of switching. Because the parameters subject to each other, it is very important for pro ducing high quality diode to choose the proper Pt diffusion temperature.
