irf9640 is a N-channel type MOSFET transistor, its main device parameters are; rated voltage of 200V, the maximum can withstand 200V voltage, this high rated voltage means that the transistor can be applied to the circuit design of large voltage; rated current of 11A, of which the maximum can withstand a current of 44A (can not be a long time in the state), this maximum current This maximum current means that irf9640 can provide very good protection performance; maximum power can reach 125W, high power means high heat, so we must pay attention to the design of the PCB after the heat dissipation; and has a very small on-resistance, which means that in the use of the process of power supply energy provided by the power supply can be converted into most of the power supply circuit application of energy. The main application circuits are power amplifier circuits, switching power supply circuits and high-power motor control circuits.

The irf9640 is a frequently used P-channel MOSFET in a TO-220AB package (the advantage of this package is that it is easy for soldering and heat dissipation, and can be connected to an external thermal pad), with a maximum withstand voltage of 200V, which makes it suitable for use in medium- and high-voltage circuit designs; it has a very low on-resistance of 0.5 ohm, which means that the resistance in the on-circuit situation is only 0.5 ohm, implying a low additional energy consumption, making this transistor have excellent energy efficiency; it has a low switching time of about 300ns, which means that it is very suitable for use in high-frequency switching circuits; due to the excellent performance of this transistor it is usually used in switching circuits. The additional consumption of energy, making this transistor has excellent energy efficiency; has a low switching time of about 300ns, which means that it is very suitable for high-frequency switching circuits; due to the excellent performance of the transistor, it is usually used in DCDC switching circuits, power switches and high-current motor drives. Use in the matters to be noted are, to ensure that the gate drive voltage is less than the rated voltage, to avoid damage to the device; used in high-power applications should pay attention to the heat dissipation, with the use of thermal pads or coated with thermally conductive silicone grease; and to consider a good anti-static protection to prevent electrostatic breakdown.
