Littelfuse P-1U-L Fixed Voltage Multiport SIDACtor Protection Thyristors are designed to protect sensitive Subscriber Line Interface Circuit (SLIC) devices from damaging overvoltage transients. The P-1U-L Series from Littelfuse provides a high surge current rated dual port protection solution incorporating a fixed voltage switching threshold for negative surges. All positive surges are routed through an internal diode to a ground reference. These thyristors can replace four discrete components offering low voltage overshoot and a low on-state voltage. The components are lead-free, halogen-free, and RoHS compliant.
