The Bourns CDNBS08-SRDA12-4 is a steering diode/TVS array combination designed for surge and ESD protection in electronic systems. It provides unidirectional protection for up to four I/O ports, making it suitable for a variety of data interface applications.
Key electrical specifications include a working peak voltage of 12V, a minimum breakdown voltage of 13.3V at 1mA, and a maximum clamping voltage of 19V at IP 1 VF. Under an 8/20 μs surge, the clamping voltage is 25.9V at a peak pulse current of 27A, with a peak pulse power rating of 500W. The device offers ESD protection per IEC 61000-4-2 with contact discharge ratings from ±8kV to ±30kV and air discharge ratings from ±15kV to ±30kV. Maximum leakage current is 1μA at the working voltage, and capacitance is 15pF at 0V and 1MHz.
The device is housed in an 8-lead narrow body SOIC package (8-SOIC) and is surface mountable. It is RoHS compliant and has a flammability rating of UL 94V-0. The operating temperature range is -55°C to 150°C, making it suitable for demanding environments.
Typical applications include Ethernet (10/100 Base T), computer I/O ports such as SCSI, FireWire, and USB, set-top box protection, and video cards. The device meets IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (Surge) requirements.
