IRF7307TRPBF is a type of transistor array specially designed for high power and high current applications. It is a dual-channel N-channel MOSFET with a drain-source voltage rating of 55V, a maximum current of 25A and a source-drain resistance of 17mΩ. As a type of field-effect transistor, it is mainly used for switching and amplification.

Application Field

IRF7307TRPBF is widely used in automotive, industrial and consumer settings. It is designed to be particularly applicable in high-current low-voltage applications, such as power supplies, audio amplifiers, and DC-DC conversion. Additionally, this device is suitable for use in switched-mode power supplies (SMPS) as well as in radio frequency (RF) amplifiers, due to its low on-resistance and low voltage switch.

Working Principle

This N-channel transistor array is driven by voltage, and works by using the impact of voltage on an arrow on the surface of the semiconductor. When voltage is applied to this arrow, the electrons within its oxidation level can move freely, thus forming a conducting path between source-drain. Depending on the polarity of the applied voltage, the current will flow in either a positive or a negative direction.

The IRF7307TRPBF has two pull-down transistors and two pull-up transistors integrated onto the same chip. The two pull-down transistors are used to turn the whole device “ON”, while the two pull-up transistors turn the whole device “OFF”. Furthermore, the transistor has a gate protected by a gate voltage clamp. The fetch can work up to 60V and can protect against overvoltage. The IRF7307TRPBF can be used in an array, meaning that multiple chips can be connected together for higher power output.
