They feature a true operating voltage of Pb-Free, Halogen Free, RoHS/WEEE Compliant 3.3 volts for superior protection when compared to tra- Nominal Dimensions: 0.6 x 0.3 x 0.25 mm ditional pn junction devices. Lead Finish: NiAu Clamp3311Z is in a 2-pin SLP0603P2X3A package. Marking : Marking code It measures 0.6 x 0.3 mm with a nominal height of only Packaging : Tape and Reel 0.25mm. Leads are finished with lead-free NiAu. Each device will protect one line operating at 3.3 volts. It Applications gives the designer the flexibility to protect single lines in applications where arrays are not practical. The Cellular Handsets & Accessories combination of small size and high ESD surge capability Keypads, Side Keys, Audio Ports makes them ideal for use in portable applications such Portable Instrumentation as cellular phones, digital cameras, and MP3 players.
