Littelfuse, a global manufacturer of industrial and electronic components, has released the Pxxx0S3H SIDACtor Protection Thyristor Series, the first 2-kA surge protection component available in a compact DO-214AB (SMC) package.
Designed for applications with high transient surge exposure, including electric vehicle (EV) battery charging systems and solar inverters, this series supports system downsizing while maintaining robust electrical protection.
The Pxxx0S3H Series is engineered for ac and dc power line protection in environments where reliability and space efficiency are critical. It offers high surge current handling and long-term performance consistency, making it suitable for EV infrastructure, industrial power systems, and renewable energy platforms.
The device supports compliance with IEC 61000-4-5 Level 4 surge immunity standards, often required in high-reliability and outdoor-rated equipment.
This thyristor series provides a compact alternative to larger TO-262 devices, allowing engineers to reduce board space without compromising performance. Compared to traditional metal oxide varistors (MOVs) or gas discharge tubes (GDTs), the Pxxx0S3H maintains electrical characteristics across multiple surge events, improving overall durability and service life.
Features:
- 2-kA (8/20 μs) surge rating in a DO-214AB footprint
- Semiconductor-based architecture with no degradation over time
- Helps meet IEC 61000-4-5 Level 4 requirements
- Miniaturized dimensions (6.22 mm × 7.11 mm × 2.62 mm) for space-constrained designs
- Standalone or hybrid deployment alongside MOVs as needed
Applications include battery systems and EV wall charging units, solar inverters and energy storage platforms, industrial and automation power supplies, UPS and AC distribution equipment, IoT-enabled power control systems, and others.
The Pxxx0S3H Series supports the development of more compact, durable, and application-specific protection schemes for the next generation of electrified systems, including those powering transportation and distributed energy resources.
