In addition to the general parameters of SMD diode, SMD diode for different purposes also have other different characteristics. The following briefly introduces the basic characteristics of rectifier diodes and detector diode:
1. Rectifier diode
Rectifier diode are mainly used in rectifier circuits, that is, to convert alternating current
Pulsating direct current. Rectifier diode are all junction type, so
The large junction capacitance makes its operating frequency lower. Generally below 3kHZ
under.
2. Detector diode
The main function of the detector diode is to remove the low frequency signal in the high frequency signal.
Number check out. Their structure is point contact type. Its junction capacitance is relatively
Small, high working frequency, generally made of germanium materials.
