The IRFPF30PBF is a specific N-Channel MOSFET (short for Metal-Oxide-Semiconductor Field-Effect Transistor) designed and manufactured by International Rectifier. It occupies a position in the middle of the Category of Single MOSFETs. The specific type of FET being discussed is a discrete single-die, low profile (3mm) package.

Application field of IRFPF30PBF MOSFET

The IRFPF30PBF offers two distinct advantages in its application, namely: its level of high current capacity, and its ease of integrability with Secondary Side devices, making it ideal for boards with limited space. It can offer a high level of current carrying capacity, and due to its low profile design, it can be easily mounted on small PC boards. The IRFPF30PBF can be used in a range of applications and industries including:

• HVAC and Power Quality Applications
• Amplification and Power Conditioning
• ISDN/DSL Power Management
• DC-DC and Off-Line Switchers
• DC motor Drivers
• Telecommunication Systems
• Automotive Electronics
• Surge Protection
• High Frequency Applications

Working Principle of IRFPF30PBF MOSFET

The MOSFET is a voltage-controlled device that operates on the principle of minority carrier injection. It allows a given external voltage to control the on-state current, thereby offering an efficient and controllable switching media. When an external voltage is applied to the gate terminal, it produces a reverse electric field that drives the conduction between source and drain by raising the number of available electrons of majority carriers in the channel. Since there is no physical contact between gate and channel, the gate signal has no direct connection with the device, thus reducing the possibility of electrical damage.

The IRFPF30PBF MOSFET operates over a wide temperature range (-55°C to 175°C) with a maximum output voltage of 30V and maximum current of 8A. It is designed for low on-state resistance using the advanced thermal resistance technology from International Rectifier. It also has a guaranteed peak current rating of 40A and maximum power dissipation at 150W per package. The IRFPF30PBF operates in an operating temperature range of -55°C to 175°C, making it suitable for applications in extreme temperature ranges.

In addition, the IRFPF30PBF has a safety feature that allows the current to be limited in the event of a short circuit or overcurrent. This safety feature is known as the ‘snapback’ or ‘crowbar’ feature and is used to control the output current in the event of an overcurrent or short circuit. The limit is set at 10A over the rated current limit of 8A. This feature ensures that the device does not overload and allows the designer to set limits on the output current.

Overall, the IRFPF30PBF provides a reliable and efficient platform for achieving high-current capacity while minimizing the risk of electrical damage. With its wide operating temperature range and advanced thermal resistance technology from International Rectifier, the IRFPF30PBF offers the designer excellent control over their output current and reliable performance.
