Extremely low capacitance bidirectional TVS diodes

With the TVS diodes D3V3Z1BD2CSP from Diodes, Rutronik presents an ESD protection component with an extremely low capacitance Cd of 0.3pF. They have been specially created to protect high-speed differential lines. Due to their high pulse peak current capability (10.5A, tP = 8/20µs), these components can also protect against EOS. The DSN housing with 0.6mm x 0.3mm x 0.3mm also allows flexible protection for a single cable in applications. Potential uses include automotive applications needing specific change control, i.e. parts qualified to AEC-Q100/101/104/200, PPAP capable and manufactured in IATF 16949 certified facilities.

The TVS diodes provide an extremely low terminal voltage (5V or 5.3V) to protect sensitive inputs and outputs and a low reverse current of 50nA max at a VR of 3.3V. They allow reliable, bidirectional ESD protection for a cable.

They provide transient protection for the protected line according to IEC 61000-4-2 (ESD) air ±20kV, contact ±20V and IEC 61000-4-5 (overvoltage) 10.5A (8/20µs). They are completely lead-free and fully RoHS-compliant, as well as halogen- and antimony-free.

Application examples include USB3.0, USB3.1 and USB3.2 Gen 2 x 2, USB Type-C, HDMI1.4, HDMI 2.0 and HDMI 2.1, Thunderbolt 2, Thunderbolt 3, 10G Ethernet, and WiFi-6 AnT.
