Discover how these components safeguard critical electronic systems while preserving signal integrity, ensuring seamless data communication in modern automotive design.
Nexperia has unveiled an expansion to its ultra-low capacitance electrostatic discharges (ESD) protection diodes, specifically engineered to safeguard high-speed data lines within automotive infotainment applications. ESD diodes protect critical electronic systems and subsystems by dissipating the high energy of electrostatic discharges. This protects vital SOCs (system on chip) and other components from getting damaged during an ESD event. Adding additional components to a high-speed data line can deteriorate the signal integrity of the transferred data. Therefore, choosing the right components that protect the system but do not hamper the signal transmission is vital to modern high-speed automotive systems.
These additions encompass the PESD18VF1BLS-Q, PESD24VF1BLS-Q, PESD30VF1BLS-Q, and PESD32VF1BLS-Q, all encased in the DFN1006BD-2 package. This packaging design facilitates optical inspection during automotive production due to its side wettable flanks. The PESD18VF1BBL-Q, PESD24VF1BBL-Q, and PESD30VF1BBL-Q variants are available in the compact DFN1006-2 package. All these versions come in leadless packages, enhancing electrical performance and signal integrity while promoting miniaturisation in automotive design.

The company has a long-standing expertise in being the market leader and offering the best ESD protection solutions. Keeping the needs of design engineers as well as the automotive systems in mind, it is offering this portfolio with the best-in-class signal integrity performance enabled by the ultra-low device capacitance (as low as a typical 0.28 pF) combined with the higher standoff voltage of 18-32 V for placement closer to the connector. For maximum design flexibility, these diodes are offered both with and without side wettable flanks, with the side wettable flanks enabling automated optical inspection (AOI).
NFC (near field communication) antenna protection preserves NFC antenna performance in devices, ensuring reliable contactless communication. It also safeguards high-speed data lines, vital for data integrity, using surge protection and signal conditioning to maintain seamless digital communication. These AEC-Q101 automotive-qualified devices exhibit extremely deep snapback behaviour combined with a low dynamic resistance of 0.8Ω for improved system-level robustness and clamping performance in high-speed data interfaces.
