These 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 also offer leading ESD and RF performance, and save PCB space.
Nexperia offers silicon-based ESD protection for the CAN-FD bus in both leaded and leadless packages. The DFN1412D-3 and DFN1110D-3 leadless DFN packages with side-wettable flanks occupy 80% less PCB space than traditional SOT23 and SOT323 packages. Despite this, products assembled in this package feature improved thermal behaviour due to a larger internal lead frame that includes a heatsink and thermal pad.
PESD2CANFDx diodes are also very ESD robust delivering improved system level protection performance. This is because the parts have industry’s lowest clamping voltages of only 33 V at IPP = 1 A and low dynamic resistance of 0.7 Ω. Nexperia ESD protection devices also offer very good RF switching parameters featuring a mixed mode insertion loss of just +20 dB at 300 MHz, leading to excellent signal integrity.
