Recognition of Insulated Layer Gate MOSFETs
Insulation layer gate type MOSFET alias MOSFET (hereinafter referred to as MOSFET), which has a cable sheath of silicon dioxide in the middle of the gate voltage and source drain. MOSFET is also N-channel and P-channel two categories, but each category is divided into en... -
How to determine whether a MOSFET is good or bad?
There are two ways to tell the difference between a good and bad MOSFET: The first: qualitatively distinguish the advantages and disadvantages of MOSFETs First use the multimeter R × 10kΩ block (embedded 9V or 15V rechargeable battery), the negative pen (black) connected... -
Ideas to solve the serious heat generation of MOSFETs
I do not know if you have found a problem, MOSFET act as a switching power supply equipment during operation sometimes serious heat, want to solve the heating problem of MOSFET, first we need to determine what causes, so we need to test, in order to find out where the pr... -
The role of MOSFETs in circuits
MOSFETs play a role in switching circuits is to control the circuit on and off and signal conversion.MOSFETs can be broadly divided into two categories: N-channel and P-channel. In the N-channel MOSFET circuit, the BEEP pin is high to enable the buzzer response, and lo... -
Take a look at MOSFETs
MOSFETs are insulating MOSFETs in integrated circuits.MOSFETs, as one of the most basic devices in the semiconductor field, are widely used in board-level circuits as well as in IC design.The drain and source of MOSFETs can be inte... -
Basic MOSFET identification and testing
1.Junction MOSFET pin identification The gate of the MOSFET is the base of the transistor, and the drain and source are the collector and emitter of the corresponding transistor. The multimeter to R × 1k gear, with two pens to measure the forward and reverse resistance b... -
Causes and Prevention of MOSFET Failure
The two main causes of MOSFET failure: Voltage failure: that is, the BVdss voltage between the drain and source exceeds the rated voltage of the MOSFET and reaches a certain capacity, causing the MOSFET to fail. Gate Voltage Failure: The gate suffers an abnormal voltage ... -
What can I do to fix my MOSFET that is heating up badly?
Power supply circuits, or power supply circuits in the field of propulsion, inevitably use MOSFETs, which are of many types and have many functions. For switching power supply or propulsion applications, it is natural to use its switching function. Regardless of N-type o... -
MOSFET conduction characteristics
MOSFET conductivity means that it is used as a switch, which is equivalent to a switch closing.NMOS is characterised as conducting when Vgs exceeds a limited value, which applies to the condition with the source connected to a grounded device, and only needs the gate vol... -
MOSFET Operating Characteristics
In fact, from the name, the power MOSFET is that it can work again when the output current is larger, MOSFET classification is divided into many kinds, which around the characteristics of the power consumption we can be divided into enhancement and depletion of type, if ... -
Analysis of the reasons for the ineffectiveness of MOSFET
At this stage in the application of the industry, the application of the first ranked consumer electronics device adapter goods. Ranked second are computer motherboards, computer adapters, LCD monitors and other commodities. Ranked third is the communication net... -
Parameter analysis and measurement of MOSFETs
There are many kinds of main parameters of MOSFET, which contain DC current, AC current parameters and limit parameters, but the general application only need to care about the following basic parameters: saturation state of the leakage source current IDSS pinch-off volt...
