IRF9640 MOSFET Explained / Description

IRF9640 is a P channel MOSFET manufactured in TO-220 and other packages. The continuous drain current of the transistor is -11A therefore you it can drive maximum load of -11A through the transistor with the maximum load voltage of -200V. The transistor can be used for wide variety of switching and amplification purposes. It is also capable to deliver fast switching speed hence can be used in applications where fast switching is crucial. The drain to source resistance of the transistor is 0.500. The minimum the source resistance the lesser power is waste which makes the transistor power efficient. Moreover the transistor has low driving requirements which make it capable to be derived directly from ICs, microcontrollers and electronic platforms such as Arduino.



Where We Can Use it & How to Use

IRF9640 can be used for verity of general purpose requirements that falls under its characteristics. Other than that it can also be used for fast switching requirements and also in audio amplifier application. Using this MOSFET is pretty much same as you use any other general purpose MOSFET.

How to Safely Long Run in a Circuit

For long term performance with this device use it 20% below from its maximum ratings. The maximum continues drain current -11A therefore do drive load of more than -8.8A. The maximum drain to source voltage is -200V therefore do not drive load of more than -160V, use a suitable heatsink with this transistor and always store or operate the transistor in temperature above -55 degree Celsius and below +150 degree Celsius.
