美格SLM730 ＆ SLM750模块能否将5V电压通过二极管降压后给模块供电?
不建议采用这种供电方式，二极管压降随电流变化而变化，会导致模块供电电压不稳定。
请问是否可以准确的测出一颗二极管是肖特基二极管，还是普通PN结二极管，或者是SIC二极管？
可通过Trr参数判断。SIC二极管电压600V规格以上，相当于零反向恢复时间。肖特基二极管一般是250V以内，一般反向恢复时间是40ns以内。快恢复二极管的Trr可以做到几百ns级别，但大多PN结二极管的反向恢复时间是微秒级别以上。
只有齐纳二极管的反向特性,能否说明正向特性?
其正向特性和一般二极管相同，如硅二极管,大约具有0.6V的正向导通特性。但是, 齐纳二极管的正向特性没有测定,因此不作保证。
buck电路中续流二极管有哪些推荐的，输出24V10A
一般推荐肖特基二极管或者快恢复二极管，推荐选用肖特基二极管，因为拥有更低的导通压降，参数选择这块，电流参数选择是正常工作的1.5-2倍，电压选择正常工作时的1.2倍，所以续流二极管的具体参数选型还需要BUCK电路的输入电压参数。
150W小体积电源，PFC中更换续流二极管后，MOS和二极管温度一起变高，这是什么原因？
不同二极管反向恢复特性不同，反向恢复电流过大会引起MOS和二极管开关损耗增大，温度变高。小体积高功率密度电源可以尝试使用SiC二极管，反向恢复电流可忽略不计，能够大大降低开关损耗，减少发热。
