Littelfuse, Inc. Fixed Voltage TwinSLIC™ in Modified DO-214AA P1501CB2L

This fixed voltage, unidirectional, modified DO-214 SIDACtor thyristor series is designed to protect SLICs (Subscriber Line Interface Circuit) from damaging overvoltage transients. These components provide single port protection implementing voltage switching characteristics for negative polarity surges and a clamping diode for positive polarity surges. All positive surges are routed through internal diodes to a ground reference. Applicable Global Standards: TIA-968-A TIA-968-BITU K.20/21 Enhanced Level* ITU K.20/21 Basic Level GR 1089 Inter-building* GR 1089 Intra-building IEC 61000-4-5 2nd edition YD/T 1082 YD/T 993 YD/T 950 * Series resistance required Low voltage overshoot Low on-state voltage Does not degrade surge capability after multiple surge events within limit Fails short circuit when surged in excess of ratings Integrated diodes for positive voltage surges Single-port protection RoHS Compliant and Halogen-free Pb-free E3 means 2nd level interconnect is Pb-free and the terminal finish material is tin(Sn)(IPC/JEDEC J-STD-609A.01)
