Teccor Electronics P1100SA RP Sidactor Solid State Protector

Teccor Electronics P1100SA RP Sidactor Solid State Protector is a Sidactor solid‑state surge protector designed to clamp fast transients on signal and power lines. As part of Littelfuse’s Sidactor family, it combines silicon‑avalanche protection with a thyristor device to provide rapid, self‑contained overvoltage protection without moving parts. The RP suffix denotes a reel‑pack variant of the P1100SA, typically offered in the DO‑214AA form factor suitable for surface‑mount assembly. The P1100SA itself is rated for a 90 V peak off‑state voltage (Vdrm), making it appropriate for circuits requiring protection against voltages up to about 90 V. When a transient exceeds its triggering threshold, the SIDACTor conducts and clamps the voltage, then latches to continue conducting until the surge subsides, thereby protecting downstream components. Common applications include protecting telecommunications equipment and data interfaces from fast transients; the Sidactor data book describes these devices as silicon‑based protection elements used for rapid response to high‑energy transients on telecom lines and similar interfaces, and they are part of Littelfuse’s broader SIDACTOR lineup used across industrial and consumer electronics protection networks.
