The CD143A-SR12 is a steering (rail-to-rail) TVS diode array from Bourns designed to protect sensitive electronic circuits from electrostatic discharge (ESD), electrical fast transients (EFT), and surge events. It meets IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (Surge) requirements. The device provides protection for Vcc and two data lines.
Key electrical specifications include a working peak voltage of 12 V, a minimum breakdown voltage of 13.3 V at 1 mA, and a maximum clamping voltage of 19 V at 1 A and 30 V at 16 A. The peak pulse power rating is 500 W for an 8/20 µs pulse, with a peak pulse current of 16 A. Leakage current is 1.0 µA at 12 V, and capacitance per data line is 10 pF at 0 V and 1 MHz.
The device is housed in a SOT-143 surface-mount package (TO-253-4/TO-253AA) measuring 2.80 mm x 1.20 mm. It is designed for direct mounting on FR4 printed circuit boards. The operating temperature range is -55°C to +150°C. The component is lead-free, RoHS compliant, and halogen-free.
Typical applications include Ethernet (10/100/1000 Base-T), Firewire, USB, portable electronics, and video/graphic cards. The diode array is also suitable for general ESD protection in portable electronic devices such as cell phones and handheld electronics.
