The leads are spaced at RoHS/WEEE Compliant a pitch of 0.5mm and are finished with lead-free Nominal Dimensions: 2.5 x 1.0 x 0.58 mm NiPdAu. They are designed for easy PCB layout by Lead Finish: NiPdAu allowing the traces to run straight through the device. Each device features four TVS diodes with an operat- Molding compound flammability rating: UL 94V-0 ing voltage of 5 volts and a maximum loading capaci- Marking : Marking code tance of only 10pF.
