P-4U-L Multiport SIDACtor Protection Thyristors

Littelfuse P-4U-L Multiport SIDACtor Protection Thyristors are designed to protect baseband equipment from overvoltage transients. Targeted for voice through DS-1 applications, the components provide a dual port surface mount solution that enables equipment to comply with various global regulatory standards. The P-4U-L parts can replace four discrete components. Surge capability does not degrade after multiple surge events within limit. The MS-013 packaged thyristors feature low voltage overshoot, low on-state voltage, low capacitance, and fails short circuit when surged in excess of ratings. The components are lead-free and RoHS compliant.

Baseband Voice DS1 SIDACtor Protection Thyristors

Littelfuse Baseband Voice DS1 SIDACtor® Protection Thyristors focus on addressing the performance and regulatory requirements of baseband telecommunications equipment such as voice, modems, and DS1. SIDACtor components are solid state crowbar devices designed to protect telecom equipment during hazardous transient conditions. Utilizing a patented ion implant technology, effective protection is ensured within nanoseconds. The components offer an overvoltage protection solution that helps applications comply with Telcordia GR-1089 Issue 4, ITU-T recommendations K.20, K.21, K.44, and K.45, and TIA-968-A.

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.

A-U-6L & P-6UAL SIDACtor Protection Thyristors

Littelfuse A-U-6L and P-6UAL SIDACtor® Balanced Multiport Protection Thyristors are designed to protect baseband equipment from overvoltage transients. The patented “Y” configuration ensures balanced overvoltage protection that prevents longitudinal to differential conversions. The A-U-6L and P-6UAL parts can replace six discrete components and offer two-port protection. Surge capability does not degrade after multiple surge events within limit. The MS-013 packaged thyristors feature low voltage overshoot, low on-state voltage, low capacitance, and fails short circuit when surged in excess of ratings. The components are RoHS compliant, lead-free, and meet UL/IEC 60950-1 creepage and clearance.
