什么是快恢復(fù)二極管(FRD)
是對pn結(jié)二極管采取縮短反向恢復(fù)時(shí)間(trr)對策的二極管,也叫高速二極管。
為了對開關(guān)電源等用途的幾十kHz至幾百kHz等高頻進(jìn)行整流而制造,與普通整流二極管相比,trr要小2~3個(gè)數(shù)量級。
典型特性
耐壓(VRM) 600V,800V,1000V等高耐壓
正向電壓(VF) 1.3V~3.6V左右
反向電流(IR) 幾μA~幾十μA,非常小
反向恢復(fù)時(shí)間(trr) 幾十nS~100nS左右
用途 高壓開關(guān)回路(PFC等)的整流等
反向恢復(fù)時(shí)間越小,VF就越大,因此需要根據(jù)用途,選用最適合的類型。
