FEATURES
Dedicated
protection, this device can provide both voltage
protection and current limitation with a very tight
tolerance.
Itshigh surgecurrentcapabilitymakesthe L3100B
a reliable protection device for very exposed
equipment,or when series resistorsare very low.
Thebreakdownvoltagecan beeasilyprogrammed
byusingan externalzenerdiode.
A multipleprotection mode can also be performed
when using several zener diodes, providing each
lineinterfacewith an optimizedprotectionlevel.
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
thelevelof thedesiredcurrent.
