D1031SH45TS02   二极管

二极管是用半导体材料(硅、硒、锗等)制成的一种电子器件 。二极管有两个电极，正极，又叫阳极；负极，又叫阴极，给二极管两极间加上正向电压时，二极管导通， 加上反向电压时，二极管截止。 二极管的导通和截止，则相当于开关的接通与断开 。
二极管具有单向导电性能，导通时电流方向是由阳极通过管子流向阴极。
二极管是早诞生的半导体器件之一，其应用非常广泛。特别是在各种电子电路中，利用二极管和电阻、电容、电感等元器件进行合理的连接，构成不同功能的电路，可以实现对交流电整流、对调制信号检波、限幅和钳位以及对电源电压的稳压等多种功能 
无论是在常见的收音机电路还是在其他的家用电器产品或工业控制电路中，都可以找到二极管的踪迹 


A diode is an electronic device made of semiconductor materials (silicon, selenium, germanium, etc.). A diode has two electrodes, the positive electrode, also known as the anode; The negative electrode, also known as the cathode, conducts when a forward voltage is applied between the two poles of the diode, and turns off when a reverse voltage is applied. The conduction and cutoff of a diode are equivalent to the on and off of a switch.
Diodes have unidirectional conductivity, and during conduction, the current direction flows from the anode to the cathode through the tube.
Diodes are one of the earliest semiconductor devices, and their applications are very extensive. Especially in various electronic circuits, reasonable connections between diodes, resistors, capacitors, inductors, and other components can be used to form circuits with different functions, which can achieve various functions such as AC rectification, detection of modulated signals, limiting and clamping, as well as stabilizing power supply voltage
Whether it is in common radio circuits, other household appliances or industrial control circuits, the traces of diodes can be found
