Brief introduction to the transistor: Transistor, the full name should be the semiconductor transistor, also known as bipolar transistor, crystal transistor, is a current control current of semiconductor devices and its role is to enlarge t...
How to do a good selection of components
Failure rate of components with time change process can be described by a similar bathtub curve failure rate curve, early failure rate increases with time and the rapid decline in life (or random failure period) in failure rate basically un...
What is the forward current rating of the diode?
The rated current of the diode is the main nominal value, such as the 5A/100v diode, the 5A is the rated current. Typically the rated current is defined as the average current rating of the diode. But some of the test is Fang Bo, that is, th...
Common problems of NPN type transistor
Usually someone will ask such a question: the collector of a NPN type transistor is connected to the positive electrode, the emitter is connected to the negative pole, the base is not connected to any end of the power supply, and the collec...
The possible reasons detailed MOS tube heating
In the application of switching power supply, the application of MOS is required to conduct regular and off. For example, the basic buck converter used in DC-DC power supply relies on two MOS tubes to perform the switching functions, which...
