关于二极管反向恢复时间问题?
当用二极管进行整流时,除考虑他的功率和耐压值外,还要考虑他的反向恢复时间,请问各位大侠,什么什么反向恢复时间啊?为什么要考虑他的反向恢复时间呢?请告知,谢谢!!!!

Trr
Trr:Another parameter which can be used to determine the
speed of the rectifier is the reverse recovery time (trr ). This
is measured from the instant the current passes through
zero (from forward to reverse) to the instant the current
recovers to either 10% or 25% of its peak reverse value.
Low reverse recovery times are associated with low
stored charge devices.
