Programmable Transient Voltage Suppressor For Slic Protection

This device L3121B has been especially designed to pro- tect a subscriber line Interface circuit (SLIC) with an integrated ring generator. Used with the recommended application circuit, each line (TIPand RING) is protected againstposi- tive and negative surges. In the positive polarity, the breakdown voltage is referenced to the + VB , and in the negativepolarity, the breakdownvoltage is referencedto the -Vbat . Its high surge current capabilitymakes the L3121B a reliableprotectiondevice for veryexposed equip- ment, or when series resistors are very low. By STMicroelectronics
