Meet Slkor's SLPESD0402–30 🚗⚡ - The Ultra-Low Capacitance ESD Diode Powering the Future of High-Speed Automotive Connectivity

 Slkor Semiconductor, a leading innovator in core semiconductor solutions, today unveiled a powerful new addition to its high-performance, ultra-low capacitance ESD protection diode lineup — the SLPESD0402–30.

 Engineered for precision and reliability, this compact device delivers superior protection for high-speed data lines in space-limited automotive electronics, making it an ideal choice for ADAS sensor interfaces, in-vehicle camera systems, compact infotainment modules, and next-generation high-speed automotive networks.

The SLPESD0402–30 adopts an industry-leading 0402 micro surface-mount package. Its leadless design not only saves valuable PCB space — perfectly matching the trend toward miniaturization in automotive electronics — but also enhances electrical performance and signal integrity, making it ideal for use in ultra-compact designs.

Electrostatic discharge (ESD) remains one of the biggest threats to the reliability of automotive electronics. The core mission of the SLPESD0402–30 is to rapidly dissipate high-energy ESD surges, effectively shielding key backend components such as SoCs (System-on-Chips) and precision devices from potential damage. However, protection on GHz-speed data lines must not compromise signal quality.

Leveraging its deep technical expertise in ESD protection, Slkor Semiconductor designed the SLPESD0402–30 with ultra-low junction capacitance (a typical value of only 0.05 pF) and a working voltage (VRWM) of 30 V — a combination that delivers a significant competitive edge. Its extremely low capacitance minimizes signal distortion in LVDS, MIPI, GMSL, and in-vehicle Ethernet systems, ensuring flawless data integrity. The 30V VRWM allows safe operation in 12V and 24V automotive power systems, enabling first-line protection close to connectors.

To meet the stringent reliability standards of automotive electronics, the SLPESD0402–30 provides an impressive clamping voltage (VC) of up to 40V and ultra-low leakage current (IR typical value of 10 nA), significantly reducing static power loss. Fully AEC-Q101 compliant, the device also offers excellent clamping efficiency, fast recovery, and low dynamic resistance (typical 0.8 Ω), enhancing overall system-level robustness under ESD conditions (IEC 61000–4–2 standard).

Finally, its mature automated 0402 assembly process ensures efficient, high-yield mass production, perfectly suited for modern automotive manufacturing lines.
