< Back DMOS Product Line Linear Systems Mar 17, 2023 DMOS Product Line Acquired from Vishay/Siliconix DMOS Product Line Linear Systems Re-Launches DMOS Product Line Acquired from Siliconix FREMONT, CA - 04/02/2020 Linear Systems announces the re-release of the SD-Series lateral DMOS switch product line acquired from Vishay/Siliconix in 2001. Built using the industry-leading proprietary DMOS process developed by Siliconix and transferred to Linear Systems, the SD-series uses lateral construction to achieve low capacitance and ultra-fast switching speeds (1ns max). “Our lateral DMOS products continue the tradition established by Siliconix with its design and production of these devices,” Mr. Tim McCune said. “The DMOS parts we produce meet every specification established by Vishay/Siliconix when they made them. The customers who relied on Siliconix for these parts transitioned smoothly to using ours, and we’ve welcomed many new customers since then.” These lateral DMOS switches are key components in a variety of high-performance analog circuits where ultra-fast, nano-second switching times are critical. Linear Systems is the only company to build these lateral DMOS parts using Siliconix’ proprietary polysilicon gate technology and is the only Vishay/Siliconix-approved replacement manufacturer. This fabrication process is key to the unique combination of speed and reliability of these parts. Linear Systems in 2001 reached an agreement with Vishay/Siliconix to produce these lateral DMOS parts after Vishay decided to exit that business. Under that agreement, LIS received mask sets, and process and technical information for the SD210, SD214, SST211, SST213, SST215, SD5000, SD5001, SD5400, and SD5401 product families from Siliconix. These parts are available in thru-hole, surface mount, die, ROHS, and Non-ROHS(Lead) for medical and military applications. Special testing is also available. “This line of lateral DMOS has been critical to a large number of high-end product developers, and it was important to Vishay that these customers not be forced to design these parts out, or use inferior ones,” McCune said. McCune noted Linear Systems’ lateral DMOS parts are used in a wide variety of military applications that require Non-ROHS parts as well as civilian applications. “The key performance parameters – switching time, low capacitance– are important in all applications,” he said. This product line is supported by an in-depth application note, detailed data sheets and recently developed SPICE models in the LTspice® format.

< Back CMR Ratio in Dual JFETs Introduction When choosing the optimal JFET for a new circuit, a characteristic often overlooked is how the part’s design affects the rejection of unwanted inputs while amplifying the signal as accurately as possible. Single JFETs provide excellent impedance matching and low-noise amplification, but lack one important quality of their dual counterparts – dual discrete devices largely reject common signals. This important characteristic – Common Mode Rejection – means that selecting the right dual JFET can be the most cost-effective way of improving signal-to-noise ratio in a design. Read More

< Back What are Current Regulating Diodes Linear Systems Oct 7, 2024 Current regulating diodes, also known as constant current diodes or current limiting diodes, are electronic components that control the amount of electrical current flowing through a circuit. They work by maintaining a constant voltage across themselves despite changes in the load resistance. Current Regulating Diodes Current regulating diodes, also known as constant current diodes or current limiting diodes, are electronic components that control the amount of electrical current flowing through a circuit. They work by maintaining a constant voltage across themselves despite changes in the load resistance. How do they work? A standard diode allows current to flow freely in one direction and blocks it in the other direction. In contrast, a current regulating diode has a larger depletion region and a lower reverse breakdown voltage, which allows for more precise control of the current flow. When used in series with a load, the current regulating diode maintains a stable voltage drop across itself by varying its own resistance depending on the current flow. This means that as the load resistance changes, the voltage drop across the diode remains constant and therefore maintains a consistent current flow. Applications Current regulating diodes are commonly used in circuits where stable and precise current control is necessary, such as in LED lighting systems, battery charging circuits, and laser diode drivers. They can also be used as protection devices to limit the amount of current flowing through sensitive components. In addition, these diodes are often utilized in adjustable power supplies to regulate the output current and prevent damage to connected devices. Types of Current Regulating Diodes There are two main types of current regulating diodes: Zener diodes and avalanche diodes. Zener diodes operate in the reverse breakdown region, where they maintain a constant voltage despite changes in current flow. This makes them ideal for use as voltage regulators. Avalanche diodes, on the other hand, operate in the avalanche breakdown region and are used for higher voltage applications. They have a steeper current-voltage characteristic compared to Zener diodes, allowing for more precise control of the current flow. Advantages and Disadvantages The main advantage of using current regulating diodes is their ability to provide stable and accurate current control without the need for additional external components. This saves space and simplifies circuit design. However, one disadvantage is that these diodes can be sensitive to changes in temperature, which can affect their current regulation capabilities. In addition, they have a limited maximum current handling capacity, so they may not be suitable for high power applications. Conclusion In conclusion, current regulating diodes are essential components in many electronic circuits where precise and stable current control is necessary. They come in various types and offer advantages such as simplicity of use and compact size. However, care must be taken when using these diodes to ensure proper operation under different conditions. With continued advancements in technology, it is likely that we will see further improvements and developments in the field of current regulating diodes. So next time you encounter a circuit that requires precise current control, consider using a current regulating diode to achieve optimal performance. With their unique properties and benefits, these diodes are sure to play a significant role in the future of electronics. With the ever-growing demand for more efficient and reliable electronic devices, it is important to have a thorough understanding of different electronic components such as current regulating diodes. By having knowledge about their operation, advantages and limitations, you can make informed decisions when designing circuits for various applications. So keep exploring and learning about these fascinating components and discover new ways to incorporate them into your designs.
