TE Connectivity’s business in **protection circuit** solutions has introduced the **2Pro AC** innovative hybrid device, specifically designed for sensitive downstream electronics. This device offers protection against damage caused by overcurrent and overvoltage events, eliminating the need for manual resetting. The 2Pro AC integrates a **polymer positive temperature coefficient (PPTC)** device with a **thermally enhanced metal-oxide varistor (MOV)** into a single compact package. This integration not only improves reliability but also reduces component count and simplifies the design process, making it ideal for low-current applications like **LED lighting, smart meters, home appliances, and power supplies**.
A diagram illustrates the device’s structure and functionality, showcasing its compact design and efficient performance. The 2Pro AC is particularly useful in energy-saving applications where power supply instability or lightning strikes can cause surges that damage sensitive electronics.
By combining **reconfigurable PPTC** and **MOV technologies**, the 2Pro AC offers a significant advantage over traditional methods. Unlike conventional approaches that require replacing **fused MOVs** after a fault or involve complex board layouts that may lead to thermal instability, the 2Pro AC provides a **resettable and stable solution**. Its thermal coupling mechanism ensures that the varistor surface temperature remains below **150°C**, preventing thermal runaway and extending the life of the device.
Guo Weiqing, Global Product Manager at TE Circuit Protection, emphasized: “With the increasing use of energy-efficient systems like LED lighting, devices are more vulnerable to damaging surges from unstable power sources or lightning. The 2Pro AC delivers a reliable, space-saving, and user-friendly protection solution that outperforms traditional discrete methods.â€
The 2Pro AC meets industry standards such as **IEC 61000-4-5** and **IEC 60950**, helping manufacturers streamline compliance testing, including **UL 60950**. It is also **RoHS compliant** and **halogen-free**, ensuring environmental safety and regulatory adherence. This makes it an excellent choice for designers looking for a robust and sustainable protection solution for modern electronic systems.
