AT THE ELECTRONICA TRADE FAIR IN MUNICH November 11-14, Protek will debut an electrostatic discharge (ESD) circuit protection diode for industrial applications such as assembly line automation, access control systems, machinery, and more. The overvoltage protection component is designed to protect two industrial CAN lines from ESD and other electrical fast transients (EFT).

The product is also suitable for circuit protection in other industrial applications such as those using Devicenet bus lines. ESD protection is > 25 kV. The component features 200 W of peak pulse power per line. In addition, it provides a low clamping voltage, low capacitance, and low leakage current. It is also compliant with the RoHS and Reach standards.

The diode is provided in a molded Jedec SOT-23 package that has an approximate weight of eight milligrams. Other mechanical characteristics include lead-free pure-tin plating (annealed) and a solder reflow temperature of 260 °C to 270 °C. The recommended operating and storage temperature ranges are -55 °C to 150 °C.

The diode is now available in mass quantities. Pricing varies by the number of units per order. The parts are available in 3000 unit minimums in eight millimeter tape and reel, per EIA standard 481.
