Diodes Deliver Reliable ESD protection On High-Speed Data Lines

Expanding the CeraDiode 0402 and 0603 product lines, the latest offerings report low capacitances with typical values of 0.6 pF, making them suitable for ESD-protection chores on high-speed data lines such as USB, Ethernet, FireWire, eSATA, and HDMI. The 0402 and 0603 case sizes correspond to Zener and TVS diode case sizes SOD-723 and SOD-523, making them one-to-one replacements. The diodes specify a response time of less than 0.5 ns and exhibit no temperature derating up to an operating temperature of +85°C. Response voltage is 5.6 Vdc and the Types CDS2C05HDMI1 (0402) and CDS3C05HDMI (0603) pass HDMI 1.3-compliance testing. Pricing varies considerably depending on type and quantity.
