A relay is an electronic device that primarily controls larger currents or voltages by inputting small currents or voltages into a circuit. This device mainly consists of an electromagnetic coil, a switch, and a spring. When current passes through a coil, it generates a magnetic field that attracts the switch and causes it to close. In this way, larger currents or voltages can flow through the switch. When the current stops flowing, the spring will push the switch back to its original position a

A bidirectional trigger diode (also known as a bidirectional thyristor, bidirectional thyristor, or DIAC) is an electronic component that can conduct electricity in two directions. Unlike unidirectional trigger diodes (DIACs), bidirectional trigger diodes do not have an "anode" and a "cathode", but instead have two electrodes, commonly referred to as A1 and A2 or MT1 and MT2. Its characteristic is that it has similar electrical characteristics in both directions. Bidirectional trigger diodes ar

Magneto sensitive diode is a semiconductor device based on magnetic sensing effect, also known as magnetoresistance or magnetic resistance. When a magnetic sensitive diode is subjected to a magnetic field, the flux lines of the current inside the conductor are twisted, thereby changing the resistance value of the material. By measuring the change in resistance value, the strength of the magnetic field can be determined. It has the advantages of high sensitivity, fast response speed, small size,

A Fast Recovery Diode (FRD) is a semiconductor device specifically designed to quickly switch from a conducting state to a cutoff state in a circuit. Compared to traditional rectifier diodes, fast recovery diodes have a shorter reverse recovery time (TRR), which makes them highly suitable for high-frequency and high-speed switching applications, such as switching power supplies, frequency converters, and power electronic conversion devices. Fast recovery diodes can reduce switching losses and im
