STB140NF75 - N-Channel MOSFET by STMicroelectronics

The STB140NF75 is a robust N-Channel MOSFET designed and manufactured by STMicroelectronics, a leader in semiconductor solutions. This power MOSFET is a part of ST's STripFET™ II series and is widely recognized for its high efficiency and excellent on-state resistance. The STB140NF75 is primarily aimed at high-current, high-speed switching applications, making it an ideal choice for power supplies, DC-DC converters, motor control circuits, and more.

With a maximum drain-source voltage (V<sub>DS) of 75V, and a continuous drain current (I<sub>D) of 120A at 25°C, this MOSFET can handle significant power. Its low threshold voltage ensures that the device can be driven at lower gate voltages, which enhances its suitability for low-voltage applications. The STB140NF75 also boasts an extremely low on-state resistance (R<sub>DS(on)) of just 0.008 Ohm, contributing to its high efficiency by minimizing conduction losses.

Key features of the STB140NF75 include:

• 100% avalanche tested, providing reliable operation even under harsh conditions.
• Exceptional thermal performance due to its maximum junction temperature of 175°C.
• Low gate charge (Q<sub>g) which results in faster switching performance and reduced switching losses.
• Compatible with standard gate driving voltages, which simplifies the design of driving circuits.

The device is housed in a TO-220 package, which is well-known for its durability and ease of mounting on a printed circuit board. The TO-220 package also provides excellent heat dissipation characteristics, ensuring the MOSFET operates within safe temperature ranges under high current conditions.

Whether you're designing power management systems, automotive electronics, or high-performance computing hardware, the STB140NF75 offers the reliability, efficiency, and power handling capabilities to meet the demands of your applications. STMicroelectronics' commitment to quality ensures that the STB140NF75 is a product you can rely on for consistent performance and longevity.
