Double ESD circuit protection diode for network devices
ProTek Devices has introduced a double electrostatic discharge circuit protection diode suited for networking applications such as Ethernet, smartphones and cellular phones and audio/video inputs.

The PESD3V3 provides 25A SSC at 8/20 μs to protect communications application from the effects of spurious surges. It is compatible with IEC standards 61000-4-2 (ESD): air ±30kV, contact ±30kV, 61000-4-4 (EFT), and 61000-4-5 (surge): 25A. It provides 400 W peak pulse power per line and can protect two unidirectional lines or one bidirectional line. In addition, it has a leakage current of < 2.0 μA and low capacitance with a rated standoff voltage of 3.3 V. Operating and storage temperatures ranges from -55 to 150 degrees Celsius. The new diode is RoHS and REACH compliant.

Now available, the PESD3V3 is provided in a molded JEDEC SOT-23 package and Protek cites the weight as approx 8mg. Other key mechanical characteristics include lead-free pure-tin plating (annealed) and a solder reflow temperature (pure-tin Sn) of 260-270 degrees Celsius. The device’s flammability rating is UL 94V-0. It is delivered on 8mm tape and reel, per EIA standard 481, in minimum quantities of 3,000.
