Introduction

IRF720STRL is an enhanced high-performance N channel MOSFET developed by International Rectifier Corporation that offers high power gain, high immunity to latch-up, and improved drain-to-source ESD protection. It operates at a relatively high breakdown voltage, up to 80V, allowing universal consumer electronics applications including computers, laptops, and home appliance components. With its wide operating temperature range between -40℃ to +125℃, it also finds extensive use in automotive and agricultural applications. This paper will look at the different application field and working principles of IRF720STRL.

Application Field

IRF720STRL has several applications, primarily in consumer and automotive electronic products. The features of this part provide it a unique advantage that can be used for multiple applications and products.In consumer electronics, IRF720STRL is used in the design and construction of various components, such as transistors, relays, and amplifiers. It is also used as a switch in power supplies and battery-operated circuits. It is an ideal choice for low voltage/current applications, such as laptop and desktop computers, telecom systems, and factory automation.On the automotive side, IRF720STRL finds use in a variety of applications. It is extensively used for DC relays and controllers in electric vehicles, allowing for efficient operation in start/stop applications. Additionally, it is often used in motor controllers, power supplies, and other various circuits found in automobiles.

Working Principle

IRF720STRL is a N-Channel MOSFET, which means it consists of a semiconductor material with an insulated gate and a p-type channel. When the gate voltage is increased, the transistor is turned on, and current flows through the channel. As the voltage is decreased, the transistor is turned off, and current stops flowing. The breakdown voltage of IRF720STRL is 80V, which is relatively higher compared to other MOSFETs. This allows for more reliable performance and higher efficiency in most applications. Additionally, it also has a wide operating range, between -40℃ to +125℃, allowing it to be used in both high and low temperature applications. The device also has high immunity to latch-up, meaning it can be used in sensitive applications, such as medical equipment and industrial instruments. Furthermore, this part also offers improved drain-to-source ESD protection, allowing it to be reliably used in portable unit applications.

Conclusion

This paper has discussed the different application field and work principles of IRF720STRL. This device is an ideal choice for low current/voltage applications, such as computers and home appliance components, as well as various automotive components, including motor controllers and DC relays. It offers high power gain, high breakdown voltage, high immunity to latch-up, and improved drain-to-source ESD protection. The wide operating temperature range between -40℃ and +125℃ also makes it suited for both high and low temperature applications.
