L3100B1
FEATURES
UNIDIRECTIONAL FUNCTION PROGRAMMABLE BREAKDOWN VOLTAGE UP TO 265 V PROGRAMMABLE CURRENT LIMITATION FROM 50 m A TO 550 m A HIGH SURGE CURRENT CAPABILITY IPP = 100A 10/1000 µs DESCRIPTION
Dedicated to sensitive tele equipment protection, this device can provide both voltage protection and current limitation with a very tight tolerance. Its high surge current capability makes the L3100B a reliable protection device for very exposed equipment, or when series resistors are very low. The breakdown voltage can be easily programmed by using an external zener diode. A multiple protection mode can also be performed when using several zener diodes, providing each line interface with an optimized protection level. The current limiting function is achieved with the use of a resistor between the gate N and the cathode. The value of the resistor will determine the level of the desired current.
