L3100B Datasheet PDF - STMicroelectronics

DESCRIPTION
Dedicated to sensitive telecom 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 voltagecan beeasily programmed by using an external zener diode.
