CLP270M

® CLP270M OVERVOLTAGE AND OVERCURRENT PROTECTION FOR TELECOM LINE PRELIMINARY DATASHEET Application Specific Discretes A.S.D.™ MAIN APPLICATIONS Any telecom equipment submitted to transient overvoltages and lightning strikes such as : Analog and ISDN line cards PABX Main Distribution Frames Primary protection modules DESCRIPTION The CLP270M is designed to protect telecommunication equipment. It provides both a transient overvoltage protection and an overcurrent protection. It is housed in a PowerSO-10TM package. FEATURES DUAL BIDIRECTIONAL PROTECTION DEVICE. HIGH PEAK PULSE CURRENT : Ipp = 100A (10/1000 µs SURGE) Ipp = 500A (2/10 µs SURGE) MAX. VOLTAGE AT SWITCHING-ON : 380V MIN. CURRENT AT SWITCHING-OFF : 150mA FAILURE STATUS OUTPUT PIN BENEFITS Both primary and secondary protection levels in one device. Voltage and current controlled suppression. Surface Mounting with PowerSO-10TM package. Line card cost reduction thanks to the very low power rating of external components required : balanced resistors, ring relay, low voltage SLIC protection. Falls into short circuit if destroyed, still ensuring protection.
