LITTELFUSE Pxxx0S3N SIDACtor Protection Thyristor Series safeguards exposed interfaces in industrial and ICT applications, including RS-485 data interfaces and ac-dc power supplies. Available in a compact, DO-214AB (SMC) package, devices provide 3kA (8/20) high-power surge protection with low thermal accumulation during long-term overvoltage events. A vital advantage of the device is that the switching voltage (VS) is much lower than Gas Discharge Tubes (GDT), and the on-state voltage (VT) is much lower than Metal Oxide Varistors (MOV) and Transient Voltage Suppressor (TVS) Diodes.
