Nexperia launches AEC-Q101-qualified, leadless CAN-FD protection diodes

Semiconductor manufacturer Nexperia has announced new leadless ESD protection devices for CAN-FD applications. Devices are available in leadless packages with side-wettable flanks that enable AOI tools to be used. Fully AEC-Q101-qualified, the PESD2CANFDx series parts are designed to provide ESD and RF performance, and save PCB space.

Nexperia says its new DFN1412D-3 and DFN1110D-3 leadless DFN packages with side-wettable flanks occupy 80% less PCB space than traditional SOT23 and SOT323 packages while delivering improved thermal behavior due to a larger internal lead frame that includes a heatsink and thermal pad.

The company says its PESD2CANFDx diodes are ESD-robust because the parts have low clamping voltages of 33 V at IPP = 1 A and low dynamic resistance of 0.7 Ω. Nexperia also says its ESD protection devices offer very good RF switching parameters, featuring a mixed-mode insertion loss of +20 dB at 300 MHz.

Product manager Lukas Droemer said, “CAN-FD is an important bus in automotive in-vehicle networks, but devices must be protected against ESD. Another essential requirement for automotive applications is the ability to use AOI. Our new devices in leadless packages meet both these requirements, providing a high-performance alternative to leaded SMD packages. The PESD2CANFDx series fulfills all CAN-FD specification requirements and exceeds the requirements of AEC-Q101 by two times.”

20 devices are available now in the DFN1412D-3 and DFN1110D-3 packages for automotive and industrial applications, including CAN/CAN-FD, FlexRay, SENT and LVDS.
