FEATURES
DESCRIPTION
Dedicated to
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.
