IRC Develops SOIC & SOT-23 Packaged Diode Arrays to Deliver IEC-Compatible Transient Voltage Suppression

Providing designengineers with a compact means of protecting one to eight circuit tracesagainst electrostatic discharge (ESD), lightning and other electrical fast transient(EFT) events, TT electronics IRC has developed a comprehensive series of IEC-compatibleTVS diode arrays in 8-, 14- or 16-pin SOIC-N and SOT-23 surface mount packages.Available in unidirectional and bidirectional versions, the diode arrays arecapable of ESD protection of <40kV and carry a peak pulse power rating of500W (t_P = 8/20Amus).

IRC's QDN Series TVS diode arraysprovide protection to IEC standards for a variety of transient voltage events,including: IEC 61000-4-2 - ESD protection to 15kV (air) / 8kV (contact); IEC61000-4-4 - EFT protection to 40A @ 5/50ns; and IEC 61000-4-5 - lightning/surgeprotection to 12A @ 8/20Amus for Level 2 (line-to-ground) and Level 3(line-to-line).

Specific applications for the TVS diodearrays include: low-voltage ASICs,wireless communications circuits in mobile phones and portable electronics;dataport protection for RS-422, RS-432 and RS-485 lines; Ethernet 10/100 Base-Tand other LAN/WAN equipment; as well as communications circuits in desktop computersand other microprocessor-based systems.
