  SLCE1005A015FR: A New Benchmark for ESD Protection in High-Frequency Circuits with 0603 Package

Slkor introduces the SLCE1005A015FR ESD protection diode, specifically designed for high-frequency electronic devices. With its ultra-small 0603 package and ultra-low capacitance characteristics, it provides reliable electrostatic protection for high-frequency links such as HDMI 1.3, high-speed Ethernet, and USB 2.0, effectively resisting electrostatic discharge (ESD) and transient interference, ensuring stable operation of devices in complex electromagnetic environments.

The core advantage of this device lies in its precise protection and signal compatibility in high-frequency scenarios: adopting thick-film technology and bidirectional protection design, it has a junction capacitance (Cp) of only 0.15pF (typical value), which has negligible impact on signal transmission at 1MHz, perfectly adapting to high-frequency applications such as 3.4GHz (e.g., HDMI 1.3 interface); the insertion loss is extremely low, only -0.25dB at 3.4GHz, ensuring the integrity of high-speed data transmission. Meanwhile, its fast response time (<1ns) can instantly suppress overvoltage interference, with a typical TLP clamping voltage (V_C (TLP 30)) of 40V, combined with a trigger voltage (V_T (TLP)) of 250V, building a solid*for circuits.

In terms of protection performance, the SLCE1005A015FR has passed stringent international standard certifications: compliant with IEC 61000-4-2 Level 4, with contact discharge reaching 8kV (typical) and 15kV (maximum), and air discharge reaching 15kV (typical) and 25kV (maximum). It can withstand more than 100 ESD strikes while maintaining stable performance; the maximum leakage current (I_L (MAX)) is only 10μA@14V DC, with extremely low static power consumption, extending the battery life of portable devices.

The package and reliability design are also impressive: it adopts an ultra-small 0603 package (dimensions 1.50-1.70mm×0.70-0.90mm×0.40-0.60mm), saving nearly 30% of circuit board space compared to traditional packages, suitable for high-density layouts; it supports standard reflow soldering processes, withstanding high-temperature soldering at 260℃/10s, and has passed multiple environmental tests such as humidity, thermal shock, and vibration. The operating temperature range is -55℃ to +125℃, meeting the requirements of long-term stable operation in harsh environments.

In terms of application scenarios, the SLCE1005A015FR is compatible with core areas of high-frequency electronic devices:

● In consumer electronics, it protects the RF links of smartphone antennas, GPS modules, and Bluetooth devices from electrostatic interference;

● It is suitable for display and communication interfaces such as HDMI 1.3, DVI, and USB 2.0, ensuring uninterrupted 4K video and high-speed data transmission;

● It provides protection for high-speed Ethernet ports and printer interfaces of industrial equipment, resisting electromagnetic transients in factory environments.

"The breakthrough of SLCE1005A015FR lies in balancing 'ultra-low capacitance' and 'high protection' in the 0603 package," said the head of Slkor's protection devices division. "High-frequency circuits are extremely sensitive to parasitic parameters. Through material innovation and structural optimization, we enable the device to provide 42V DC operating voltage protection without affecting signal integrity, which is exactly a precise response to the trend of 'high-frequency and miniaturized' electronic devices."

Currently, the SLCE1005A015FR has achieved stable mass production and supports bulk supply.
