If you’re an electronics enthusiast, engineer, or hobbyist working with Infineon components, staying informed about discontinued products is crucial. This list covers some of the notable Infineon parts that have been phased out, providing details on their functions, why they were popular, and what alternatives exist. Whether you’re retrofitting old designs or seeking replacements, this guide helps you navigate the landscape of discontinued Infineon products effectively.
1. Infineon TLE6208GP
The TLE6208GP was a high-current, full-bridge driver designed for motor control applications, especially in automotive and industrial settings. It featured a robust H-bridge configuration capable of handling up to 3A per channel, making it ideal for controlling DC motors in various embedded systems. Infineon discontinued this product as newer, more efficient driver ICs with integrated protections and lower power consumption became available, but many legacy systems still rely on it due to its durability and performance.
2. Infineon IR2110
The IR2110 is a high-voltage, high-speed power MOSFET and IGBT driver with level-shift and high/low-side outputs, commonly used in motor drives, inverters, and power supplies. Its ability to handle up to 600V made it a favorite for medium-voltage switching applications. Infineon phased out the IR2110 in favor of newer driver ICs like the IRS2000 series, which offer improved efficiency, integrated protections, and easier interface options, but the IR2110 remains in many operational systems.
3. Infineon TLE4941
The TLE4941 was a magnetic field sensor designed for precise position sensing in automotive and industrial applications. It provided accurate Hall-effect measurements, crucial for motor control and current sensing. Infineon discontinued the TLE4941 as they developed newer, more sensitive magnetic sensors like the TLI4970, which offer better linearity and lower power consumption, but the TLE4941 is still valued in legacy designs.
4. Infineon PEF 6000
The PEF 6000 series was a family of power electronic modules used in motor drives and power conversion systems. These modules integrated multiple IGBTs and diodes, simplifying design and assembly. Infineon phased out these modules in favor of the more advanced PrimePACK and EconoDUAL series, which provide higher current ratings, better thermal management, and improved reliability, yet some older systems still depend on PEF 6000 modules.
5. Infineon TDA2030
The TDA2030 is a classic audio power amplifier IC, popular for its simplicity and reliability in home audio and small speaker systems. It could deliver up to 14W of output power with minimal external components. Infineon discontinued the TDA2030 as newer Class-D amplifiers with higher efficiency and integrated features became prevalent, but it remains a go-to component for vintage audio projects.
6. Infineon BSC010NE2LS
The BSC010NE2LS is a logic-level N-channel MOSFET used in switching power supplies and motor controllers. Its low Rds(on) and high-speed switching capabilities made it a favorite for efficient power management. Infineon phased out this model as newer MOSFETs with even lower Rds(on) and higher current ratings entered the market, but it still appears in some legacy circuits.
7. Infineon IRFP240
The IRFP240 is a power N-channel MOSFET widely used in switching power supplies, inverters, and motor drivers. Its high voltage rating (200V) and robust construction made it popular in DIY and industrial applications. Infineon discontinued the IRFP240 in favor of newer devices like the IRFP460 and other high-performance MOSFETs that offer lower gate charge and better thermal characteristics.
8. Infineon TLE4279
The TLE4279 is a low-dropout voltage regulator designed for automotive applications, providing a stable voltage supply in harsh environments. It featured overcurrent and thermal protection, making it suitable for sensitive electronic modules. Infineon phased out the TLE4279 as newer LDO regulators with lower dropout voltages and higher efficiency became available, but it remains in many older automotive systems.
9. Infineon TLE6208G
The TLE6208G was a quad low-side driver for automotive and industrial motor control, capable of driving inductive loads with integrated overcurrent protection. It was appreciated for its robustness in harsh environments. Infineon discontinued this model as more integrated driver solutions with smart diagnostics and higher current capacities emerged, though it’s still in use in legacy setups.
10. Infineon XC2000 Series
The XC2000 series was a family of microcontrollers tailored for automotive and industrial control applications, featuring integrated peripherals and real-time capabilities. As Infineon transitioned to the AURIX family, the XC2000 series was phased out. However, these microcontrollers are still in operation in older machinery, making their discontinuation noteworthy for legacy system maintenance.
How to Choose
When selecting replacement components for discontinued Infineon products, consider key factors like voltage and current ratings, package type, thermal management, and compatibility with your existing design. It’s also essential to evaluate the availability of newer alternatives that offer improved efficiency, integrated protections, and easier integration. Understanding your application’s specific requirements—such as switching speed, power dissipation, and environmental conditions—will help you identify the most suitable current products.
Frequently Asked Questions
- Are discontinued Infineon products still safe to use? Yes, if they are still functioning correctly and meet your system requirements. However, they may lack modern protections and efficiencies.
- Can I find replacements for discontinued products? Often, yes. Infineon and other manufacturers offer newer models with improved features that serve as suitable replacements.
- Why does Infineon discontinue products? Discontinuations typically result from technological advancements, supply chain considerations, or the introduction of better-performing alternatives.
- What should I do if my system uses a discontinued product? Evaluate whether the product still meets your requirements or if an upgrade to a newer component is advisable for improved reliability and performance.
- Are old discontinued products still supported? Support varies by product; some legacy products may still have limited technical support, but official manufacturing support generally ends after discontinuation.
Final Thoughts
Understanding which Infineon products have been discontinued helps in managing existing designs and planning future upgrades. While some legacy components remain functional and reliable, staying informed about newer alternatives ensures your projects benefit from the latest innovations. Whether you’re maintaining old equipment or designing new systems, knowing the lifecycle of these components can save time, reduce costs, and improve overall system performance.
