It is unidirectional device and may be used on lines where the signal polarities are above ground. The UESD54B/55B/64B will protect up to four lines, the UESD56B will protect up to five lines and the UESD57B will protect up to six lines. TVS diodes are solid-state devices feature large cross-sectional area junctions for conducting high transient currents, specifically for transient suppression. It offers desirable characteristics for board level protection including fast response time, low operating, low clamping voltage, and no device degradation. The UESD54B/55B/56B/57B/64B may be used to meet the immunity requirements of IEC 61000-4-2, level 4. The small package makes them ideal for use in portable electronics such as cell phones, PDA’s, notebook computers, and digital cameras. Applications Features Cellular Handsets & Accessories Cordless Phones Personal Digital Assistants (PDA’s) Notebooks & Handhelds Portable Instrumentation Digital Cameras Peripherals MP3 Players Transient protection for data & power lines to IEC 61000-4-2 (ESD) ±15kV (air), ±8kV (contact) Working Voltages: 5V Low Leakage current Low clamping voltage Solid-state silicon avalanche technology Ordering Information Part Number Working Voltage Packaging Type Channel Marking Code Shipping Qty UESD54B 5.0V SC70-5/SC88A/SOT353 4 UQ5 UESD55B 5.0V SC89-6/SOT563/SOT666 4 UF5 UESD56B 5.0V SC89-6/SOT563/SOT666 5 UB5 UESD57B 5.0V DFN1616-6L 6 E57 UESD64B 5.0V SC89-5/SOT553/SOT665 4 UR6 3000pcs/ 7 Inch Reel |
