UM5202EEDF Dual Channel Low Capacitance ESD Protection Array UM5202EEDF SOT143 General Description UM5202EEDF is surge rated diode arrays designed to protect high speed data interfaces. This series has been specifically designed to protect sensitive components which are connected to data and transmission lines from over-voltage caused by ESD (electrostatic discharge). The unique design incorporates surge rated, low capacitance steering diodes and a TVS diode in a single package. During transient conditions, the steering diodes direct the transient to either the positive side of the power supply line or to ground. The internal TVS diode prevents over-voltage on the power line, protecting any downstream components. The low capacitance array configuration allows the user to protect two high-speed data or transmission lines. The low inductance construction minimizes voltage overshoot during high current surges. This device is optimized for ESD protection of portable electronics. They may be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 (± 15kV air, ± 8kV contact discharge).

When the voltage on the protected line exceeds the reference voltage the steering diodes are forward biased, conducting the transient current away from the sensitive circuitry. Data lines are connected at pins 2, 3. Pin 1 should be connected directly to a ground plane. The path length is kept as short as possible to minimize parasitic inductance. The positive reference is connected at pin 4. The options for connecting the positive reference are as follows: 1. To protect data lines and the power line, connect pin 4 directly to the positive supply rail (VCC). In this configuration the data lines are referenced to the supply voltage. The internal TVS diode prevents over-voltage on the supply rail. 2. In applications where the supply rail does not exit the system, the internal TVS may be used as the reference. In this case, pin 4 is not connected. The steering diodes will begin to conduct when the voltage on the protected line exceeds the working voltage of the TVS (plus one diode drop). Matte Tin Lead Finish Matte tin has become the industry standard lead-free replacement for SnPb lead finishes. A matte tin finish is composed of 100% tin solder with large grains. Since the solder volume on the leads is small compared to the solder paste volume that is placed on the land pattern of the PCB, the reflow profile will be determined by the requirements of the solder paste. Therefore, these devices are compatible with both lead-free and SnPb assembly techniques. In addition, unlike other lead-free compositions, matte tin does not have any added alloys that can cause degradation of the solder joint. ________________________________________________________________________ http://www.union-ic.com Rev.02 Dec.2014 3/5 UM5202EEDF Package Information UM5202EEDF SOT143 Outline Drawing 3 1 2 C L1 E1 4 E e e1 A A2 L D b A1 b2 DIMENSIONS MILLIMETERS INCHES Symbol Min Max Min Max A 0.763 1.220 0.031 0.049 A1 0.013 0.150 0.001 0.006 A2 0.750 1.070 0.030 0.043 b 0.300 0.510 0.012 0.020 b2 0.760 0.930 0.030 0.037 C 0.080 0.200 0.003 0.008 D 2.800 3.040 0.112 0.122 E 2.200 2.640 0.088 0.211 E1 1.200 1.400 0.048 0.056 e 1.920BSC 0.077BSC e1 0.200BSC 0.008BSC L1 0.540REF 0.022 L 0.400 0.600 0.016 0.024 Land Pattern 1.92 0.80 0.20 0.90 0.50 NOTES: 1.
