Dual port SLIC protectors guard against lightning induced surge and power fault events

Available now from Mouser, the Littelfuse B61089QDR and B9110DF are dual port Subscriber Line Interface Circuit (SLIC) protectors. B61089QDR protects two different SLIC tip/ring pairs with independent voltage tracking for each pair. B61089QDR protects the SLIC interface against lightning induced surge and power fault events. This SLIC protector contains fast switching crowbarring structures for negative events and a simple fast switching diode structure for positive events. B9110DF dual port polarity programmable SLIC protector protects smart ringing SLICs with dual power supplies. B9110DF protects the SLIC interface against lightning induced surges and power fault events. This SLIC protector contains fast switching crowbarring structures that are compatible with the Basic levels outlined in ITU K.20, K.21, K.45.
