Bourns Announces New Steering Diode Array Device Optimized for ESD, EFT and Surge Protection

RIVERSIDE, Calif., July 8, 2009 – Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced the introduction of a new steering diode array that provides up to six lines of protection using the “rail to rail” clamping technique with low leakage current and low capacitance per line. Designated Bourns® model CDNBS08-SR112, the lead-free steering diode device was designed specifically for ESD, EFT and surge protection applications and is RoHS compliant.* Available in an NSOIC-8 package, the new device is designed to be mounted directly onto an FR4 printed circuit board. Bourns engineers optimized the design to protect a wide range of applications including Ethernet ports, portable electronics, wireless LANs and Universal Serial Bus (USB) interface-based systems.
Bourns’ steering diode array meets IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT) and IEC 61000-4-5 (surge) requirements for external ports and features very low capacitance of 5 pF to minimize electrical distortion. The devices also meet many worldwide, industry and government regulations regarding lead-free components and are designed for a variety of manufacturing environments, allowing the use of industry-standard “pick and place” equipment. The chip diode NSOIC-8 package offers simplified production with its flat configuration that minimizes rollaway.
“Bourns’ new steering diode array provides a good choice for ESD, EFT and surge protection for up to six communication data lines and also fits circuit board space constraints,” said Ian Doyle, ESD Product Line Manager for Bourns, Inc. “Bourns is pleased to offer the newest addition to the company’s steering diode array product line that meets industry demands for smaller electronic components with extremely low power consumption.”
