UM5084 Low Capacitance Bidirectional Single Line TVS Protection Diode UM5084 DFN2 1.0×0.6 General Description The UM5084 TVS protection diode is designed to replace multilayer varistors (MLVs) in portable applications such as cell phones, notebook computers, and PDA’s. They feature large cross-sectional area junctions for conducting high transient currents, offer desirable electrical characteristics for board level protection, such as fast response time, lower operating voltage, lower clamping voltage and no device degradation when compared to MLVs. The UM5084 TVS protection diode protects sensitive semiconductor components from damage or upset due to electrostatic discharge (ESD) and other voltage induced transient events. The UM5084 is available in DFN2 1.0×0.6 (compatible with SOD923/SOD882/CSP 1.0×0.6) package with working voltages of 12 volt. It gives designer the flexibility to protect bidirectional single line in applications where arrays are not practical. Additionally, it may be “sprinkled” around the board in applications where board space is at a premium. It may be used to meet the ESD immunity requirements of IEC 61000-4-2, ±15kV air, ±8kV contact discharge.

The device is bidirectional and may be used on lines where the signal polarity is above ground and below ground. Circuit Board Layout Recommendations for Suppression of ESD Good circuit board layout is critical for the suppression of ESD induced transients. The following guidelines are recommended: 1. Place the TVS near the input terminals or connectors to restrict transient coupling. 2. Minimize the path length between the TVS and the protected line. 3. Minimize all conductive loops including power and ground loops. 4. The ESD transient return path to ground should be kept as short as possible. 5. Never run critical signals near board edges. 6. Use ground planes whenever possible. For multilayer printed-circuit boards, use ground vias. 7. Keep parallel signal paths to a minimum. 8. Avoid running protection conductors in parallel with unprotected conductor. 9. Avoid using shared transient return paths to a common ground point. ________________________________________________________________________ http://www.union-ic.com Rev.04 Mar.2016 3/5 UM5084 Package Information UM5084 DFN2 1.0×0.6 Outline Drawing DIMENSIONS D e Pin #1 ID E b(2×) R L(2×) L1 Bottom View Symbol MILLIMETERS A Min 0.40 Typ - Max 0.53 Min 0.016 Typ - Max 0.021 A1 0.00 - 0.05 0.000 - 0.002 b 0.45 0.50 0.55 0.018 0.020 0.022 D 0.95 1.00 1.075 0.037 0.039 0.042 E 0.55 0.60 0.675 0.022 0.024 0.027 A1 A e Side View INCHES 0.65TYP 0.026TYP L 0.20 0.25 0.30 0.008 0.010 0.012 L1 0.00 0.05 0.10 0.000 0.002 0.004 R 0.05 0.10 0.15 0.002 0.004 0.006 Note: R is optional.
