Meet SLCE1005A015FR - A Game-Changer in High-Frequency ESD Protection with Its Tiny 0603 Footprint

 Slkor introduces the SLCE1005A015FR ESD protection diode, designed specifically for next-generation high-frequency electronics. Featuring an ultra-compact 0603 package and ultra-low capacitance, it delivers robust electrostatic protection for high-speed interfaces such as HDMI 1.3, high-performance Ethernet, and USB 2.0. Engineered to withstand intense ESD events and transient disturbances, it ensures stable, reliable device performance even in demanding electromagnetic environments.

The core strength of this device lies in its precision protection and outstanding signal compatibility tailored for high-frequency environments. Built with advanced thick-film technology and a bidirectional protection structure, it delivers an ultra-low junction capacitance of just 0.15pF (typ.), ensuring virtually zero impact on signal transmission at 1MHz and seamless performance in 3.4GHz high-frequency applications such as HDMI 1.3. With an exceptionally low insertion loss of -0.25dB at 3.4GHz, it preserves high-speed data integrity with ease.

At the same time, its sub-1ns response time enables instantaneous suppression of transient overvoltage events. Combined with a typical TLP clamping voltage (V_C TLP 30) of 40V and a trigger voltage (V_T TLP) of 250V, it forms a robust protection barrier for sensitive circuits.

In terms of protection capability, the SLCE1005A015FR meets the industry’s most demanding standards. It complies with IEC 61000–4–2 Level 4, offering 8kV (typ.) / 15kV (max.) contact discharge and 15kV (typ.) / 25kV (max.) air discharge performance. The device withstands 100+ ESD strikes while maintaining stable characteristics. With a maximum leakage current of only 10μA @ 14V DC, it ensures ultra-low static power consumption — an important advantage for extending battery life in portable and mobile devices.

The package and reliability design of this device are equally impressive. Built in an ultra-compact 0603 package (1.50–1.70mm × 0.70–0.90mm × 0.40–0.60mm), it saves nearly 30% PCB space compared with traditional packages — ideal for today’s high-density layouts. It supports standard reflow processes, withstands 260℃ / 10s soldering, and has passed rigorous reliability tests, including humidity, thermal shock, and vibration. With an operating temperature range of -55℃ to +125℃, it ensures long-term stability even in demanding environments.

In application scenarios, the SLCE1005A015FR delivers excellent compatibility across key high-frequency domains:

● Consumer electronics: Protects RF paths in smartphone antennas, GPS modules, and Bluetooth devices from ESD interference;
 ● Display & communication interfaces: Ideal for HDMI 1.3, DVI, and USB 2.0, ensuring smooth 4K video and high-speed data transmission;
 ● Industrial equipment: Safeguards high-speed Ethernet ports and printer interfaces, resisting electromagnetic transients common in factory settings.

“The breakthrough of the SLCE1005A015FR lies in its ability to strike the perfect balance between ultra-low capacitance and high-level protection within a 0603 package,” said the head of Slkor’s protection device division. “High-frequency circuits are extremely sensitive to parasitic parameters. Through innovations in materials and structural design, we’ve enabled this device to deliver 42V DC operating voltage protection without compromising signal integrity — precisely meeting the industry trend toward high-frequency, miniaturized electronics.”
