Marked for Telecom applications — the 1500W pulse capability and 33.2V clamp are sized for lightning surge protection on telco line cards and base stations per GR-1089 or ITU-T K.20 recommendations.","metaTitle":"1.5SMB23CA Littelfuse TVS Diode, 1500W, 33.2V Clamp","metaDescription":"Littelfuse 1.5SMB23CA bidirectional TVS, 1500W peak pulse, 33.2V clamp, DO-214AA.
