The P1800SC is a SIDACtor solid-state protection device from Littelfuse designed to protect telecommunications equipment such as modems, line cards, fax machines, and other customer premise equipment (CPE). It features an off-state voltage (VDRM) of 170 V and a breakover voltage (VS) of 220 V, ensuring reliable crowbar protection. The device can handle repetitive surge currents up to 400 A (8x20 µs waveform) and offers a low on-state voltage of 4 V at 2.2 A.
This thyristor provides a holding current (IH) of 150 mA and an off-state capacitance (CO) of 60 pF typical, minimizing signal distortion. It is housed in a compact DO-214AA (SMB) surface-mount package, suitable for automated assembly. The operating junction temperature ranges from -40 °C to +150 °C, and the storage temperature from -65 °C to +150 °C.
The P1800SC is a bi-directional device, with all electrical parameters and surge ratings applying to both polarities. It helps equipment meet regulatory requirements including GR 1089, ITU K.20/K.21/K.45, IEC 60950, UL 60950, and TIA-968-A (formerly FCC Part 68).
