Littelfuse Pxxx0S3N SIDACtors are compact package, which can provide high surge current overvoltage protection

Littelfuse, Inc., an industrial technology manufacturing company dedicated to powering a sustainable, connected and safer world. The new Pxxx0S3N SIDACtor® protective thyristor family has been announced to protect exposed interfaces in industrial and ICT applications, including RS-485 data interfaces and AC/DC power supplies. The Pxxx0S3N SIDACtor series protects equipment from severe transient overvoltages in harsh environments, helping designers meet regulatory requirements

     Littelfuse, Inc introduced the new Pxxx0S3N SIDACtor protection thyristor series, which can protect the exposed interface in industrial and ICT applications, including RS-485 data interface and AC/DC power supply. Pxxx0S3N SIDACtor series protects equipment from severe transient overvoltage damage in harsh environments, helping 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.

 

     Ben Huang, senior product marketing manager of Littelfuse Protective Semiconductor Business Department, said, "The continuous demand for product miniaturization has led to the increasing demand for compact, high-power density solutions in the market. Compared with varistors and transient suppression diodes, Pxxx0S3N SIDACtor is smaller and is the first product of the same size that can provide ultra-high surge current protection in such a small package."
