Littelfuse P-S-LRP Asymmetrical Discrete Thyristors are SIDACtor® components designed to protect LCAS (Line Circuit Access Switch) devices from damaging overvoltage transients. The components provide a specialized asymmetrical overvoltage protection solution that enables equipment to comply with various global regulatory standards. Surge capability does not degrade after multiple surge events within limit. The DO-14 package thyristors feature LCAS specific tip and ring thresholds, low voltage overshoot, low on-state voltage, and fails short circuit when surged in excess of ratings. Littelfuse P-S-LRP devices are RoHS compliant, lead-free, and halogen-free.
Littelfuse A122-U-4L Asymmetrical Multiport Thyristors are SIDACtor® components designed to protect LCAS (Line Circuit Access Switch) devices from damaging overvoltage transients. The series provides a specialized asymmetrical dual port overvoltage protection solution that enables equipment to comply with various global regulatory standards. Surge capability does not degrade after multiple surge events within limit. the asymmetrical multipart thyristors offer two-port protection and can replace four discrete components. The MS-013 package thyristors feature LCAS specific tip and ring thresholds, low voltage overshoot, low on-state voltage, and fails short circuit when surged in excess of ratings. A122-U-4L devices are RoHS compliant, Lead-free, and Halogen-free.
SIDACtor® Protection Thyristors
Littelfuse SIDACtor® Protection Thyristors are thyristor devices used to protect sensitive circuits from electrical disturbances caused by lightning-induced surges, inductive-coupled spikes, and AC power fault conditions. The unique structure and characteristics of the thyristor are used to create an overvoltage protection device with precise and repeatable turn-on characteristics with low voltage overshoot and high surge current capabilities. SIDACtor components are solid state crowbar devices with a patented ion implant technology that ensures effective protection within nanoseconds. Littelfuse SIDACtor Protection Thyristors include a wide range of semiconductor protection thyristor over-voltage transient suppression devices designed to serve requirements of telecom and data networking equipment applications.
