Littelfuse, Inc. announced the launch of the Pxxx0S3H SIDACtor Protection Thyristor Series, the industry’s first 2 kA surge protection component in a DO-214AB (SMC) package. This compact solution offers robust defense against severe transient events while enabling product miniaturization—ideal for next-generation power and energy designs.
The Pxxx0S3H Series is purpose-built for AC and DC power lines in demanding environments. It provides exceptional surge immunity for applications such as industrial power supplies, automotive battery charging systems, solar inverters, UPS/AC distribution systems, and ICT equipment. With its high current handling and compact footprint, the Pxxx0S3H enables engineers to meet IEC 61000-4-5 Level 4 requirements while reducing overall device size.
Key Differentiators and Benefits include:
High Surge Capability in Compact Footprint: First 2kA (8/20 µs) surge-rated protection thyristor in DO-214AB package, significantly smaller than traditional TO-262 solutions.
Long-Term Reliability: The semiconductor-based design withstands repeated high-energy surge events without degrading, unlike legacy GDT or MOV-based devices.
Regulatory Compliance: Aids system compliance with IEC-61000-4-5 Level 4 standards for surge immunity.
Miniaturization-Ready: Compact dimensions (6.22mm × 7.11mm × 2.62mm) support dense industrial, automotive, and solar energy systems designs.
Flexible Deployment: It can be used standalone or combined with an MOV for tailored protection architectures.
Target Markets and Applications include: Industrial and factory automation power supplies; Automotive battery management and EV wall charging systems; Solar DC/AC inverter protection; Uninterruptible power supply (UPS) and high-current AC distribution; Harsh environment ICT infrastructure; Energy storage systems and IoT-connected power devices.
The Pxxx0S3H Series allows engineers to design smaller, more reliable, and longer-lasting systems without compromise by replacing bulky and degradation-prone protection components.
The Pxxx0S3H Series SIDACtor Protection Thyristors are available in tape-and-reel quantities of 3,000.
