Littelfuse Launches New Pxxx0S3N SIDACtor Protection Thyristor Series

     Littelfuse, Inc announced the launch of the new Pxxx0S3N SIDACtor  Protective thyristor series, which can protect exposed interfaces in industrial and ICT applications, including RS-485 data interfaces and AC/DC power supplies. Protect equipment from severe transient over-voltage damage in harsh environments, and help designers meet regulatory requirements.

     Pxxx0S3N SIDACtor series adopts compact DO-214AB (SMC) package, which is used to provide 3kA (8/20) high-power surge protection and reduce heat accumulation in case of long-term overvoltage. An important advantage of Pxxx0S3N is that its switching voltage (VS) is much lower than that of the gas discharge tube (GDT), and the on state voltage (VT) is much lower than that of the varistor (MOV) and transient voltage suppressor (TVS) diodes.

     Pxxx0S3N is very suitable for various applications in hazardous environments, including: DC and AC power lines in factory automation, industrial/ICT applications, power interface of energy storage system (ESS), solar energy system DC/AC inverter, UPS/AC high-power distribution network and electric vehicle (EV) charging system,

     "The constant demand for miniaturization of products has led to an increasing demand for compact, high power density solutions in the market," said Ben Huang, senior product marketing manager of Littelfuse's protective semiconductor business department. "Compared with varistors and transient suppression diodes, Pxxx0S3N SIDACtor is smaller and is the first product that can provide ultra-high surge current protection in such a small package."
