CP3121 Datasheet - STMicroelectronics

DESCRIPTION
Dedicated to the protection of sensitive telecom equipment, the LCP3121 provides protection which can be programmed by both voltage and current.
The breakdown voltage can be easily programmed by using an external zener diode.
The protection function programmed by the current is achieved with the use of a resistor between the gate and the cathode. The value of the resistor will determine the level of the desired current before the triggering of the device.

FEATURES AND BENEFITS
■ UNIDIRECTIONAL OVERVOLTAGE SUPPRESSOR PROGRAMMABLE BY VOLTAGE AND CURRENT:
■ PROGRAMMABLE BREAKDOWN VOLTAGE UP TO 100 V.
■ PROGRAMMABLE CURRENT LIMITATION FROM 120 mA TO 600 mA.
■ MULTI-LINE PROTECTION MODE : ONE DEVICE CAN PROTECT SEVERAL LINES.
■ HIGH SURGE CURRENT CAPABILITY : IPP = 100A for 10/1000 µs.
