B61089BDR, Thyristor Surge Protection Devices - TSPD SPSP, 170V, 35A SOIC, 8L, RoHS

B61089BDR Single-Port SLIC Protectors Littelfuse B61089BDR Single-Port Subscriber Line Interface Circuit (SLIC) Protectors are battery tracking protectors that protect the SLIC against lightning-induced surges and power fault events. Littelfuse B61089BDR SLIC Protectors consist of a pair of identical protection thyristors integrated with two anti-series diodes. These gated thyristor protectors have a crowbarring function, providing tracking battery protection down to -170V. The anti-series diode provides protection of positive surge events by diverting the surge energy to the ground. B61089BDR has a robust surge current capability, helping telecom and datacom products comply with different surge standards, such as Telcordia GR-1089, ITU-T K.20, K.21, and YD/T950.
