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 diode 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 surface junction type, so
The junction is a capacitor, which reduces the operating frequency. Generally below 3kHZ
under.
2. Detector diode
The main function of the detector diode is to convert the predetermined signal in the high-frequency signal
Number check out. Their structure is point contact type. Its junction capacitance is relatively
Small, high operating frequency, generally made of germanium materials.
