Littelfuse SIDACtor® High Exposure Surge Protection

Littelfuse SIDACtor® High Exposure Surge Protection products are a unique family of very robust solid state protection devices intended for use in high exposure environments. This family includes products specifically designed for primary protection such as cell and TO-220 devices. The High Surge Current family also has devices capable of meeting 5kA 8/20µs for use in extreme conditions. For enhanced secondary protection requirements, a D-rated device capable of 1000A 2/10µs is available in a DO-214 package. The High Surge Current Protection family provides an overvoltage protection solution that help applications comply with Telcordia GR-1089 Issue 4, and ITU-T recommendations K.20, K.21, K.44, and K.45.

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.

AC/DC Power Supply

Littelfuse AC/DC Power Supply is a commonly used building block in electronic designs. The components in these power supply building blocks need to be reliable and long-lasting, and Littelfuse offers a range of products that fit those requirements. This portfolio of components covers overcurrent and overvoltage protection, the power stage, and output protection. Typical applications for Littelfuse AC/DC Power Supply products include automotive, solar, industrial, manufacturing, and more.

P-3ACL Balanced SIDACtor® Protection Thyristors

Littelfuse P-3ACL SIDACtor® Primary Protection Balanced Thyristors feature a modified TO-220 package and are designed for use in primary protection applications. The components provide a single port overvoltage solution that enables applications to comply with the balance requirements of GR-974 and GTS-8700. P-3ACL thyristors offer high current protection as they do not degrade surge capability after multiple surge events within limit. P-3ACL fails short circuit when surged in excess of ratings. The RoHS Compliant components also offer low voltage overshoot and low on-state voltage.
