Protecting high-speed differential lines

Rutronik is offering Diodes’ D3V3Z1BD2CSP TVS diodes, an ESD protection component with an extremely low capacitance Cd of 0.3pF. They are designed to protect high-speed differential lines. Due to their high pulse peak current capability (10.5A, tP=8/20μs), these components can also be used to protect against electrical overload.

The 0.60 by 0.30 by 0.30mm DSN housing enables flexible protection for a single cable. Potential uses include automotive applications requiring specific change control: ie parts qualified to AEC-Q100/101/104/200, PPAP capable and manufactured in IATF 16949 certified facilities.

The diodes feature 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 enable reliable, bidirectional ESD protection for a cable.

The devices are RoHS-compliant and lead, halogen and antimony-free.

Application examples range from USB3.0 and Thunderbolt3 to 10G Ethernet and WiFi-6 AnT.
