Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Littelfuse Corporation (NASDAQ: LFUS) is a diversified industrial technology manufacturing company dedicated to powering a sustainable, connected and safer world. The company recently announced the launch of the Pxxx0S3H SIDACtor® thyristor protection series, which is the industry's first 2kA surge protection device in DO-214AB (SMC) packaging. This compact solution can achieve product miniaturization while preventing severe transient events, making it an ideal choice for next-generation power and energy designs.

The Pxxx0S3H series is specifically designed for AC and DC power lines in harsh environments. It can provide excellent surge immunity for applications such as industrial power supplies, battery charging systems, solar inverters, UPS/AC power distribution systems and ICT equipment. With its high current handling capacity and compact form factor, it helps engineers reduce the overall size of the device while meeting the requirements of IEC 61000-4-5 level 4.

Design engineers are under increasing pressure to integrate more functions into smaller packages without sacrificing safety. Ben Huang, Director of Product Marketing Management for Littelfuse's Protection Semiconductor business, said. The Pxxx0S3H series precisely meets this demand with its compact packaging, surge resistance and compliance advantages, far outperforming traditional MOV and GDT solutions whose performance will decline over time.

Main differences and advantages

Provide high surge protection capability in a compact structure: The first 2kA (8/20 μs) surge rated protection thyristor in a DO-214AB package, significantly smaller than the traditional TO-262 solution;

Long-term reliability: Unlike traditional devices based on GDT or MOV, semiconductor-based designs can withstand repeated high-energy surge events without performance degradation.

Compliance: Helps the system meet the IEC-61000-4-5 level 4 surge immunity standard;

In line with the trend of miniaturization: The compact size (6.22mm × 7.11mm × 2.62mm) supports the design of intensive industrial and solar systems;

Flexible deployment: It can be used independently or in combination with MOV to achieve a tailor-made protection architecture.

Target market and application

Industrial and factory automation power supplies;

Battery management and wall-mounted charging systems for electric vehicles

Solar DC/AC inverter protection

Uninterruptible power supply equipment (UPS) and high-current AC distribution;

ICT infrastructure for harsh environments;

Energy storage systems and power devices connected to the Internet of Things.

The Pxxx0S3H series enables engineers to design smaller, more reliable and more durable systems by replacing bulky and easily degenerated protective components.

Supply situation

The Pxxx0S3H series SIDACtor protection thyristors are supplied in reel form, with a minimum order quantity of 3,000 pieces. Samples can be obtained through authorized Littelfuse dealers around the world. For the list of Littelfuse authorized dealers, please visit Littelfuse.com.
