PROTECTION PRODUCTS - µClamp® Description µClamp® TVS diodes are designed to protect sensitive electronics from damage or latch-up due to ESD. They are designed to replace 0201 size multilayer varistors (MLVs) in portable applications such as cell phones, notebook puters, and other portable electronics. They feature large cross-sectional area junctions for conducting high transient currents. This device offers desirable characteristics for board level protection including fast response time, low operating and clamping voltage, and no device degradation. µClamp®3321ZA Features extremely good ESD protection characteristics highlighted by low typical dynamic resistance of 0.33 Ohms, low peak ESD clamping voltage, and high ESD withstand voltage (+/-15k V contact per IEC 61000-4-2). Low maximum capacitance (5p F at VR=0V) minimizes loading on sensitive cirucuits. Each device will protect one data line operating at 3.3 Volts. µClamp3321ZA is in a 2-pin SLP0603P2X3F package. It measures 0.6 x 0.3 mm with a nominal height of only 0.25mm. Leads are finished with Ni Au. The small package gives the designer the flexibility to protect single lines in applications where arrays are not practical. The bination of small size and high ESD surge capability makes them ideal for use in portable applications such as cellular phones, digital cameras, and tablet PC’s. µClamp3321ZA Ultra Small µClamp® 1-Line, 3.3V ESD Protection Features ‹‹ High ESD withstand Voltage: +/-15k V (Contact) and +/- 17k V (Air) per IEC 61000-4-2 ‹‹ Ultra-small package ‹‹ Protects one data line ‹‹ Low ESD clamping voltage ‹‹ Working voltage: 3.3V ‹‹ Low capacitance: 5p F maximum ‹‹ Low leakage current ‹‹ Extremely low dynamic resistance: 0.33 Ohms (Typ) ‹‹ Solid-state silicon-avalanche technology Mechanical Characteristics ‹‹ SLP0603P2X3F package ‹‹ Pb-Free, Halogen Free, Ro HS/WEEE pliant ‹‹ Nominal Dimensions: 0.6 x 0.3 x 0.25 mm ‹‹ Lead Finish: Ni Au ‹‹ Marking: Marking code ‹‹ Packaging: Tape and...
