Space-saving design offers Automotive Grade high surge current protection for harsh environments
ROSEMONT, IL April 15, 2025 — Littelfuse公司 (NASDAQ: LFUS), a diversified, industrial technology manufacturing company empowering a sustainable, connected, and safer world, today announced the launch of the Pxxx0S3G-A SIDACtor® Protection Thyristor Series, the industry’s first 2 kA thyristors in a compact DO-214AB (SMC) package. The Pxxx0S3G-A Series, designed to safeguard equipment in harsh environments from severe overvoltage transients, enables engineers to achieve greater product miniaturization while maintaining superior protection and compliance with regulatory standards.

“The Pxxx0S3G-A Series delivers robust high surge current protection in a compact package, enabling designers to miniaturize their products without sacrificing reliability or compliance," said Charlie Cai, Director of Product Marketing, Automotive TVS at Littelfuse. "This is especially valuable for applications exposed to high-energy surge events, including on-board chargers, EV charging stations, industrial automation power supplies, and solar inverters."
主要功能与特色
• High Surge Protection in Compact Form Factor: The Pxxx0S3G-A Series offers 2 kA (8/20 µs) surge protection in a DO-214AB (SMC) package, the smallest available form factor capable of such high-power density.
• Enhanced Design Flexibility: Compared to traditional solutions requiring a larger TO-262 package, the DO-214AB's compact size allows for easier integration into space-constrained designs, including IoT devices, high-power density industrial equipment, and medical power supplies.
• Reliability and Longevity: Unlike legacy solutions that degrade over time, the Pxxx0S3G-A Series sustains transients without degradation, ensuring long-term equipment protection and reducing maintenance costs.
• Automotive Grade Compliance: The series fully complies with AEC-Q101 standards, making it ideal for automotive applications such as On-Board Charger (OBC) protection, BEV/PHEV protection, and automotive battery charging systems.
市场与应用
The Pxxx0S3G-A Series is engineered to provide robust protection in a variety of demanding environments, including:
• Automotive and Electric Vehicle (EV) Systems: Protects OBC, BEV and PHEV battery charging systems, and EV wall chargers from high-energy surge events.
• Industrial and Factory Automation: Safeguards power supplies and high-power distribution grids in harsh operating conditions.
• Renewable Energy Systems: Ensures the reliability of solar system DC/AC inverters and energy storage systems that are exposed to fluctuating power surges.
• Information and Communication Technology (ICT): Secures sensitive equipment in uninterruptible power supplies (UPS) and AC high-power distribution grids.
与传统解决方案对比
传统解决方案由于其庞大的设计经常带来挑战，随着时间的推移，这些解决方案的性能可能会降低，从而降低其保护功效。 The Pxxx0S3G-A Series is more compact and offers a surge rating ideal for highly exposed applications. It has a clear advantage over the Pxxx0FNL 3kA SIDACtor series in the TO-262M package, requiring approximately 50% less PC board space.
This new product represents a leap forward, the first DO-214AB-sized product capable of handling a 2 kA (8/20) surge.在此改进之前，实现这样的保护级别需要更大的TO-262封装。
