ESD7331 ESD Protection Diode Micro-Packaged Diodes for ESD Protection The ESD7331 is designed to protect voltage sensitive components that require low capacitance from ESD and transient voltage events. Excellent clamping capability, low capacitance, low leakage, and fast response time, make these parts ideal for ESD protection on designs where board space is at a premium. Because of its low capacitance, the part is well suited for use in high frequency designs such as USB 2.0 high speed applications. www.onsemi.com 1 Cathode 2 Anode Features Low Capacitance 0.4 pF (Typ) Low Clamping Voltage Small Body Outline Dimensions: 0.60 mm x 0.30 mm Low Body Height: 0.3 mm Stand-off Voltage: 3.3 V IEC61000-4-2 Level 4 ESD Protection These Devices are Pb-Free, Halogen Free/BFR Free and are RoHS Compliant MARKING DIAGRAM PIN 1 X3DFN2 CASE 152AF 6 M 6 * * * * * * * M = Specific Device Code (Rotated 180) = Date Code Typical Applications * USB 2.0/3.0 * MHL 2.0 * eSATA ORDERING INFORMATION Device ESD7331MUT5G MAXIMUM RATINGS Rating IEC 61000-4-2 (ESD) Symbol Contact Air Value Unit 15 15 kV 250 mW Total Power Dissipation on FR-5 Board (Note 1) @ TA = 25C Thermal Resistance, Junction-to-Ambient RqJA 400 C/W Junction and Storage Temperature Range TJ, Tstg -55 to +150 C TL 260 C Lead Solder Temperature - Maximum (10 Second Duration) PD Package Shipping X3DFN2 (Pb-Free) 15000 / Tape & Reel For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specifications Brochure, BRD8011/D.

ON Semiconductor has developed a way to examine the entire voltage waveform across the ESD protection diode over the time domain of an ESD pulse in the form of an oscilloscope screenshot, which can be found on the datasheets for all ESD protection diodes. For more information on how ON Semiconductor creates these screenshots and how to interpret them please refer to AND8307/D. For sensitive circuit elements it is important to limit the voltage that an IC will be exposed to during an ESD event to as low a voltage as possible. The ESD clamping voltage is the voltage drop across the ESD protection diode during an ESD event per the IEC61000-4-2 waveform. Since the IEC61000-4-2 was written as a pass/fail spec for larger systems such as cell phones or laptop computers it is not clearly defined in the spec how to specify a clamping voltage % OF PEAK PULSE CURRENT 100 PEAK VALUE IRSM @ 8 ms tr 90 PULSE WIDTH (tP) IS DEFINED AS THAT POINT WHERE THE PEAK CURRENT DECAY = 8 ms 80 70 60 HALF VALUE IRSM/2 @ 20 ms 50 40 30 tP 20 10 0 0 20 40 t, TIME (ms) 60 Figure 11. 8 X 20 ms Pulse Waveform www.onsemi.com 4 80 ESD7331 PACKAGE DIMENSIONS X3DFN2, 0.62 x 0.32, 0.355P, (0201) CASE 152AF ISSUE A NOTES: 1.
