Clamp3321ZA Ultra Small Clamp 1-Line, 3.3V ESD Protection PROTECTION PRODUCTS - Clamp Description Features Clamp TVS diodes are designed to protect sensitive High ESD withstand Voltage: +/-15kV (Contact) and electronics from damage or latch-up due to ESD. They +/- 17kV (Air) per IEC 61000-4-2 are designed to replace 0201 size multilayer varistors Ultra-small package (MLVs) in portable applications such as cell phones, Protects one data line notebook computers, and other portable electronics. Low ESD clamping voltage They feature large cross-sectional area junctions for con- Working voltage: 3.3V ducting high transient currents. This device offers desir- Low capacitance: 5pF maximum able characteristics for board level protection including Low leakage current fast response time, low operating and clamping voltage, Extremely low dynamic resistance: 0.33 Ohms (Typ) and no device degradation. Solid-state silicon-avalanche technology Clamp 3321ZA features extremely good ESD protec- tion characteristics highlighted by low typical dynamic Mechanical Characteristics resistance of 0.33 Ohms, low peak ESD clamping volt- age, and high ESD withstand voltage (+/-15kV contact SLP0603P2X3F package per IEC 61000-4-2). Low maximum capacitance (5pF at Pb-Free, Halogen Free, RoHS/WEEE Compliant VR=0V) minimizes loading on sensitive cirucuits. Each Nominal Dimensions: 0.6 x 0.3 x 0.25 mm device will protect one data line operating at 3.3 Volts. Lead Finish: NiAu Clamp3321ZA is in a 2-pin SLP0603P2X3F 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 NiAu. The small pack - age gives the designer the flexibility to protect single Applications lines in applications where arrays are not practical. The combination of small size and high ESD surge capability Cellular Handsets & Accessories makes them ideal for use in portable applications such Notebook Computers as cellular phones, digital cameras, and tablet PCs.
