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

Bourns, Inc. 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 device is available now. As a pricing reference, Bourns' CDNBS08-SR112 is priced from $0.90-$0.95 in 10,000 piece quantities.
