Nexperia has announced lead-less ESD protection devices for automotive CAN-FD applications, qualified to AEC-Q101
They are the:
- PESD2CANFDxxx-QC – packaged in 1.4 x 1.2mm DFN1412D-3 (SOT8009)
- PESD2CANFDxxx-QB – packaged in 1.1 x 1mm DFN1110D-3 (SOT8015)
The 0.48mm high packages have side-wettable flanks for automated optical inspection during production, and have smaller footprints than SOT23 or SOT323 packages.
Clamping voltage is 33V at 1A, which the company claims is industry’s lowest, and dynamic resistance is 0.7Ω. “Nexperia ESD protection devices also offer very good RF switching parameters featuring a mixed mode insertion loss of +20dB at 300 MHz, leading to excellent signal integrity,” it claimed.
For heat dissipation, the package has an enlarged internal lead frame that includes a heatsink and a thermal pad.
“PESD2CANFDx series fulfils all CAN-FD specification requirements and exceeds the requirements of AEC-Q101 by two times,” said Nexperia product manager Lukas Droemer.
As well as protecting CAN, CAN-FD, FlexRay and SENT interfaces in vehicles, industrial applications including LVDS protection are foreseen.
