High Exposure Surge SIDACtor Protection Thyristors
Littelfuse High Exposure Surge SIDACtor Protection Thyristors are very robust solid-state protection devices intended for use in high-exposure environments. The family includes products specifically designed for primary protection, such as cell and TO-220 devices. The High Surge Current components also feature 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 Littelfuse High Surge Current Protection family provides an overvoltage protection solution that helps applications comply with Telcordia GR-1089 Issue 4, and ITU-T recommendations K.20, K.21, K.44, and K.45.
xEV Power Train Solutions
Littelfuse offers a wide portfolio of xEV Power Train Solutions that are suitable for automotive environments. This portfolio includes fuses, TVS diodes, diode arrays, gate drivers, high-voltage fuses, and thermal protectors. These products from Littelfuse are designed to be used in various EV sectors, such as battery management systems, traction motor inverters, onboard chargers, and the battery distribution unit.
P-SDLRP SIDACtor DO-214 Protection Thyristors
Littelfuse P-SDLRP SIDACtor DO-214 Protection Thyristors are designed to protect equipment in hostile environments from overvoltage transients. The components provide a 200A 10/1000μs rated surface mount solution that enables equipment to comply with enhanced surge requirements. The P-SDLRP thyristors offer low voltage overshoot and a low on-state voltage. Littelfuse P-SDLRP Series is lead-free, halogen-free, and RoHS compliant.
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.
