NEXPERIA INTRODUCES IN-VEHICLE NETWORK ESD PROTECTION PORTFOLIO
A variety of packages, capacitance classes and 36 V VRWM provide design flexibility for commercial vehicle applications.
Nexperia has introduced an AEC-Q101-qualified portfolio with six ESD protection devices designed to protect bus lines in automotive in-vehicle networks (IVN) such as LIN, CAN, CAN-FD, FlexRay and SENT from damage caused by electrostatic discharge (ESD) and other transients.
In contrast to the battery voltage found in cars and smaller vehicles, 24 V board nets are typically used in trucks and commercial vehicles. ESD protection devices with operating voltages typically above 32 V are required to safeguard sensitive signal lines in 24 V board nets. Addressing these requirements, Nexperia has designed this portfolio to have a maximum reverse standoff voltage of 36 V and up to 22 kV ESD protection. This performance is combined with a low clamping voltage of VCL= 48 V at IPP = 1 A to provide the best-in-class system-level robustness for IVN.
Keeping the specifications of in-vehicle networks and the ease of design in mind, Nexperia is offering this portfolio in SOT23 and SOT323 packages with three different ultra-low capacitance classes of 4.3 pF, 6 pF and 10 pF, which help ensure smooth communication between interfaces without impacting signal integrity. This combination maximizes flexibility in PCB design and offers several performance options for design engineers.
