Introduction :

5 V 至 24 V 低壓直流電源防反接、小型繼電器續流

Series :

常見的整流二極體(Rectifier Diode),主要功能是讓電流只能朝一個方向流動,廣泛應用於電源電路、保護電路及各種電子設備,屬於一般整流二極體,切換速度較慢,因此不適合高頻電路(如高頻開關電源)。

1N400X 屬於標準恢復二極體,反向恢復時間較長(約 2 µs 至 30 µs),僅適合 50 Hz / 60 Hz 工頻電源或低頻開關。若用於交換式電源(SMPS)高頻變壓器次級側或高頻 PWM 續流,會因切換損耗過大而嚴重發熱燒毀,必須改用 快恢復二極體(如 FR107) 或 蕭特基二極體(如 1N5819)。
