CLP200M
CLP200M is OVERVOLTAGE AND OVERCURRENT PROTECTION FOR TELECOM LINE manufactured by STMicroelectronics.
DESCRIPTION
The CLP200M is designed to protect telemunication equipment.It provides both a transient overvoltage protection and an overcurrent protection. It is housed in a Power SO-10TM package. FEATURES
DUAL BIDIRECTIONAL PROTECTION DEVICE. HIGH PEAK PULSE CURRENT : Ipp = 100A (10/1000 µs SURGE) MAX. VOLTAGE AT SWITCHING-ON : 290V MIN. CURRENT AT SWITCHING-OFF : 150m A FAILURE STATUS OUTPUT PIN BENEFITS Both primary and secondary protection levels in one device. Voltage and current controlled suppression. Surface Mounting with Power SO-10TM package. Line card cost reduction thanks to the very low power rating of external ponents required : balanced resistors, ring relay, low voltage SLIC protection.

APPLICATION NOTE 1. INTRODUCTION The aim of this section is to show the behavior of our new tele line protectiondevice. This device includes a primary protection level and is suitable for main distribution frames and line cards. This protection concept is explained and, in addition, the CLP200M performances are analysed when facing different surges as described in the CCITT remendations.
