Introduction to CPT40090:

CPT40090 is a device belonging to rectifier Arrays product series developed by STMicroelectronics. It is made using PowerMOS technology.

Application Field of CPT40090:

CPT40090 is a P-channel power MOSFET designed for high-voltage operation and very low on-state resistance which makes it ideal for industrial, telecom, medical and consumer application as well as for lighting applications. It can withstand high voltage stress and excess voltage conditions, making it versatile and long-lasting. It is also ideal for motor control applications where efficiency is of great importance.

Working Principle of CPT40090:

The CPT40090 is a bipolar P-channel MOSFET that combines an insulated gate with a segmented channel. It is made with PowerMOS technology which has a number of advantages. It allows for a very low on-state resistance, up to 10 % lower than a standard MOSFET, by integrally combining an insulated gate, floating gate and segmented P-channel. Furthermore, the combination of a segmented P-channel and a insulated gate enables maximum voltage condensation across the MOSFET.The CPT40090 has an internal bootstrap capacitor that allows the gate voltage to be very close to the drain voltage which is beneficial for efficiency. It also helps to reduce reverse recovery problems as well, by equipping the drain-to-source diode with lower reverse current spikes.

Conclusion:

The CPT40090 device is a member of the Rectifying Arrays product family and belongs to the STMicroelectronics range of semiconductor components. It is a high-voltage MOSFET, with low on-state resistance and a very low reverse recovery problem. This makes it ideal for a range of applications including motor control, lighting and telecom. Its internal bootstrap capacitor further enhances its efficiency.
