CLP270M

OVERVOLTAGE AND OVERCURRENT

PROTECTION FOR TELECOM LINE

MAIN APPLICATIONS

Any telecom equipment submitted to transient

overvoltages and lightning strikes such as :

s Analog and ISDN line cards

s PABX

s Main Distribution Frames

s Primary protection modules

PRELIMINARY DATASHEET

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.

SCHEMATIC DIAGRAM

FEATURES

s DUAL BIDIRECTIONAL PROTECTION DEVICE.

s HIGH PEAK PULSE CURRENT :

Ipp = 100A (10/1000 µs SURGE)

Ipp = 500A (2/10 µs SURGE)

s MAX. VOLTAGE AT SWITCHING-ON : 380V

s MIN. CURRENT AT SWITCHING-OFF : 150mA

s FAILURE STATUS OUTPUT PIN

BENEFITS

s Both primary and secondary protection levels in

one device.

s Voltage and current controlled suppression.

s Surface Mounting with PowerSO-10TM

package.

s Line card cost reduction thanks to the very low

power rating of external components required :

balanced resistors, ring relay, low voltage SLIC

protection.
