In today’s rapidly digitalized world, protecting device interfaces has become one of the biggest challenges for design engineers. Electrostatic discharge (ESD) can easily damage sensitive components, compromising both performance and long-term reliability. To meet this demand, Slkor introduces the SLPESD0603M42 — an ultra-low-capacitance ESD protection diode engineered specifically for high-speed data interfaces and RF circuits. It delivers outstanding ESD immunity while ensuring clean, stable signal transmission, offering a powerful protection upgrade for next-generation electronics.

Compliant with International ESD Protection Standards for Stable Protection

The SLPESD0603M42 has undergone rigorous IEC 61000–4–2 certification, delivering robust protection with 15kV air-discharge and 8kV contact-discharge immunity — more than sufficient for the demanding ESD requirements of both industrial equipment and consumer electronics. Its ultra-low leakage current (<10nA) ensures zero added power burden during normal operation, making it especially ideal for battery-powered and portable devices where every microamp matters.

In terms of clamping behavior, the device leverages an optimized dynamic-resistance design that reacts instantly during an ESD strike, keeping voltage safely limited at VC=40V. This rapid response shields downstream circuits from destructive surges, providing engineers with reliable, high-performance protection for next-generation hardware.

Compact Package Ideal for High-Density PCB Designs

As electronic devices continue to shrink while packing in more functionality, every millimeter of PCB space matters. The SLPESD0603M42 adopts an ultra-compact SOD-523 (0603) package — one of the smallest in the industry — making it an excellent fit for highly constrained layouts in wearables, IoT sensors, and next-gen portable devices. Its gold-plated terminals ensure outstanding solderability and meet MIL-STD-750 Method 2026 standards, delivering long-term reliability on automated SMT lines.

Additionally, the device comes in tape-and-reel packaging compatible with standard 7-inch reels, maximizing throughput on high-speed SMT production lines. With each device weighing just 0.001g, the SLPESD0603M42 is engineered for high-density PCB designs where size, efficiency, and manufacturability are all mission-critical.

Wide Application Scenarios to Meet Diverse Needs

The Slkor SLPESD0603M42 is not only ideal for conventional high-speed data interfaces but also delivers robust protection across a wide range of applications:
 Consumer Electronics: Safeguards USB and HDMI ports in smartphones, tablets, and laptops, ensuring stable connectivity and long-term reliability.
