UM5060 Bidirectional Single Line TVS Protection Diode UM5060 SOD523 General Description The UM5060 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 UM5060 TVS protection diode protects sensitive semiconductor components from damage or upset due to electrostatic discharge (ESD) and other voltage induced transient events. The UM5060 is available in SOD523 package with working voltages of 5 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, ±30kV air, ±30kV 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.01 Nov.2008 4/6 UM5060 Package Information UM5060 SOD523 Outline Drawing Symbol A A1 b c D E E1 E2 L θ millimeters Min Max 0.510 0.770 0.500 0.700 0.250 0.350 0.080 0.150 0.750 0.850 1.100 1.300 1.500 1.700 0.200REF 0.010 0.070 7°REF Inches Min Max 0.020 0.031 0.020 0.028 0.010 0.014 0.003 0.006 0.030 0.033 0.043 0.051 0.059 0.067 0.008REF 0.001 0.003 7°REF Land Pattern NOTES: 1.
