Littelfuse P-3U-L Voice-DS1 SIDACtor Protection Thyristors

Littelfuse P-3U-L Balanced Voice-DS1 SIDACtor® Protection Thyristors are designed to protect baseband equipment from overvoltage transients. The patented “Y” configuration ensures balanced overvoltage protection that prevents a longitudinal to differential conversion. The MS-013 components provide a single port surface mount solution that enables voice-through DS-1 equipment to comply with various global regulatory standards. The P-3U-L parts can replace three discrete components, and surge capability does not degrade after multiple surge events within limit. The P-3U-L thyristors from Littelfuse feature low voltage overshoot, low on-state voltage, and fail short circuits when surged in excess of ratings. The components are RoHS-compliant, lead-free, and meet UL/IEC 60950-1 creepage and clearance.
