Superior Group of Companies: Launch of LSBF862 JFET Supports Legacy Systems with Low Noise Performance

Innovative Low Noise JFET Launches to Support Legacy Systems

Linear Integrated Systems, Inc., based in Fremont, California, introduces the LSBF862, a cutting-edge N-channel JFET designed to fill the gap left by the discontinued NXP BF862. This new device offers remarkable advancements in noise performance and reliability, featuring a maximum noise performance of just 4.0nV/√Hz at 10Hz. Such low noise characteristics make the LSBF862 ideal for sensitive applications like low noise amplifiers and analog front-ends. With its higher minimum gate-source breakdown voltage of 40V and impressive input impedance, the LSBF862 not only meets but exceeds the demands of today’s electronic designs.

The discontinuation of the BF862 posed challenges for many engineers reliant on its specifications for legacy systems. The LSBF862 addresses these challenges by providing support for existing projects without the need for extensive requalification of new components. Moreover, it comes equipped with specialized testing options for critical DC parameters such as Vgs(off) and IDSS, allowing designers to customize circuit performance to meet specific project requirements. This level of adaptability is crucial for engineers looking to transition smoothly from the outdated BF862 while maintaining the integrity and functionality of their designs.

Cindy Johnson, CEO of Linear Integrated Systems, emphasizes the LSBF862’s contribution to enhancing performance and ensuring long-term supply continuity for design engineers and procurement departments. With a typical gain of 45mS and low capacitance of only 10pF, the LSBF862 is particularly advantageous for low-power applications, effectively extending battery life while offering the flexibility needed for tailored circuit designs. This launch highlights Linear Integrated Systems' commitment to delivering innovative solutions that empower engineers to achieve superior results in their projects, reinforcing the company’s position as a key player in the semiconductor industry.

In addition to its technical specifications, the LSBF862 is available in both SOT-23 packaged and bare-die versions, catering to various manufacturing preferences. Built on a radiation-tolerant JFET process, the LSBF862 ensures reliable performance even in demanding environments, making it suitable for applications in medical instrumentation and beyond. This versatility signifies a strong value proposition for customers who require high-quality components for their electronic systems.

The introduction of the LSBF862 not only marks a significant development for Linear Integrated Systems but also addresses a critical need in the market. By providing a dependable alternative to the discontinued BF862, the LSBF862 supports engineers in maintaining the performance of their legacy systems while equipping them with the tools needed for future innovations.
