SOIC & SOT-23 Packaged Diode Arrays to Deliver IEC-Compatible Transient Voltage
Tue, 11/16/2010 - 7:22am
Providing design engineers with a compact means of protecting one to eight circuit traces against electrostatic discharge (ESD), lightning and other electrical fast transient (EFT) events, TT electronics IRC has developed a comprehensive series of IEC-compatible TVS 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 are capable of ESD protection of <40kV and carry a peak pulse power rating of 500W (tP = 8/20µs). IRC's QDN Series TVS diode arrays provide protection to IEC standards for a variety of transient voltage events, including: IEC 61000-4-2 ESD protection to 15kV (air) / 8kV (contact); IEC 61000-4-4 EFT protection to 40A @ 5/50ns; and IEC 61000-4-5 lightning/surge protection to 12A @ 8/20µs for Level 2 (line-to-ground) and Level 3 (line-to-line). Specific applications for the TVS diode arrays 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-T and other LAN/WAN equipment; as well as communications circuits in desktop computers and other microprocessor based systems.
