CLP30-200B1 ASD (Application Specific Devices) Overvoltage and overcurrent protection for telecom line Features Dual bidirectional protection device High peak pulse current: I = 40 A (5/310 s surge) PP I = 30 A (10/1000 s surge) PP Max. voltage at switching-on: 290 V Min. current at switching-off: 150 mA SO-8 Description Order code The CLP30-200B1 is designed to protect telecommunication equipment. It provides both a Part Number Marking transient overvoltage protection and an overcurrent protection. CLP30-200B1RL CLP30 The external components (balanced resistors, ring relays contact, ...) needed by the CLP30- 200B1 protection concept require very low power Figure 1. CLP30-200B1 schematic diagram rating. This results in a very cost effective protection solution. TIPL TIPS 1 Main applications GND GND Any telecom equipment submitted to transient overvoltages and lightning strikes such as : GND GND Analog and ISDN line cards RINGL RINGS PABX Benefits Voltage and current controlled suppression Surface Mounting with SO-8 package Very low power rating of external components on line card: balanced resistors, ring relay, low voltage SLIC protection TRISILs are not subject to ageing and provide a fail safe mode in short circuit for a better level of protection. Trisils are used to ensure equipment meets various standards such as UL60950, IEC950 / CSA C22.2, UL1459 and FCC part 68. Trisils have UL94 V0 approved resin (Trisils are UL497B approved file: E136224 ). TM: TRISIL is a trademark of STMicroelectronics August 2006 Rev 1 1/15 www.st.com 15CLP30-200B1 Figure 2.
