Essential semiconductor specialist Nexperia has launched an AEC-Q101 qualified portfolio with six ESD protection devices (PESD2CANFD36XX-Q). They are designed to protect bus lines in automotive in-vehicle networks (IVN), such as LIN, CAN, CAN-FD, FlexRay and SENT, against damage caused by electrostatic discharge (ESD) and other transients.
As data rates increase and vehicles introduce more electrification, the need for ESD protection becomes increasingly critical. Providing the right protection for automotive modules is an ongoing challenge for design engineers.
In contrast to the battery voltage found in cars and smaller vehicles, 24V plate networks are typically used in trucks and commercial vehicles. ESD protection devices with operating voltages typically above 32 V are required to protect sensitive signal lines in 24 V board networks.
Meeting these requirements, Nexperia designed this portfolio to have a maximum reverse voltage of 36 V and ESD protection of up to 22 kV. This performance is combined with a low clamping voltage of V CL = 48 V at I PP = 1 A to provide the best system-level robustness for IVN.
Keeping in mind the specifications of vehicular networks and ease of design, 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 soft. between interfaces without affecting signal integrity.
This combination maximizes flexibility in PCB design and offers diverse performance options for design engineers.
