1 2 Description SOT23-3L (Top View) AZ5125-02S is a design which includes two bi-directional ESD rated clamping cells to protect two power lines, or two control lines, or two low speed data lines in an electronic systems. The AZ5125-02S has been specifically designed to protect sensitive components which are connected to power and control lines from over-voltage damage and latch-up caused by Electrostatic Discharging (ESD), Electrical Fast Transients (EFT), and Cable Discharge Event (CDE). AZ5125-02S is a unique design which includes proprietary clamping cells in a single package. During transient conditions, the proprietary clamping cells prevent over-voltage on the power Revision 2011/07/28 ©2011-2012 Amazing Micro. 1 www.amazingIC.com AZ5125-02S Transient Voltage Suppressing Device For ESD/Transient Protection SPECIFICATIONS ABSOLUTE MAXIMUM RATINGS PARAMETER PARAMETER RATING UNITS VDC ±5.8 V Operating Supply Voltage (pin-1,-2 to pin-3) ESD per IEC 61000-4-2 (Air) ±15 VESD ESD per IEC 61000-4-2 (Contact) Lead Soldering Temperature TSOL kV ±15 260 (10 sec.) o C Operating Temperature TOP -55 to +85 o Storage Temperature TSTO -55 to +150 o C C ELECTRICAL CHARACTERISTICS PARAMETER Reverse Stand-Off Voltage Reverse Leakage Current Reverse Breakdown Voltage ESD Clamping Voltage Channel Input Capacitance SYMBOL VRWM CONDITIONS T=25 oC ILeak VRWM = ±5V, T=25 oC.

The AZ5125-02S is designed to protect two lines Thus, the following guidelines are recommended: against
System ESD/EFT/Cable-Discharging pulses by clamping them to an acceptable reference. It provides bi-directional protection. Minimize the path length between the protected lines and the AZ5125-02S.
Place the AZ5125-02S near the input terminals or connectors to restrict transient The usage of the AZ5125-02S is shown in Fig. 1. Protected lines, such as data lines, control lines, coupling.
