【Daily Highlight】GBLC03C: The "Invisible Shield" for ESD Protection in Low-Voltage Circuits

release time:2025-07-24Author source:SlkorBrowse:2428

In an era where precision electronic devices are becoming increasingly miniaturized, the potential damage caused by electrostatic discharge (ESD) looms as an invisible threat. The GBLC03C electrostatic discharge protector from Slkor, however, stands out with its unique performance as a reliable protective barrier for low-voltage circuits. This bidirectional ultra-low capacitance TVS array is specifically designed to counter ESD interference, achieving a perfect balance between high-efficiency protection and signal integrity in a compact form factor.

Robust Protection: Comprehensive Coverage from Standards to Real-World Scenarios

The protective performance of the GBLC03C is no empty claim. It strictly complies with the IEC 61000-4-2 (ESD) standard, withstanding ±15kV air discharge and ±8kV contact discharge. Even in the face of 40A (5/50μs) electrical fast transients (EFT) and 12A (8/20μs) lightning strikes, it remains steadfast. Boasting a peak pulse power of 300W (8/20μs waveform), it erects a solid [敏感词] for circuits against extreme transient voltages.

Performance Parameters: Meticulous Engineering in a Small Package

As an ideal partner for low-voltage circuits, the GBLC03C features precisely engineered parameters. Its 3.0V rated working voltage (VRWM) is tailored for low-voltage scenarios, while the 4.0V minimum breakdown voltage (VBR) ensures it "acts only when necessary"—avoiding interference with normal operation while responding swiftly to electrostatic threats. With a static leakage current (IR) of just 2.0μA and an operating capacitance (CJ) of 0.8pF, it minimizes impact on circuit power consumption and signal transmission, making it particularly suitable for high-speed signal links.

Application Adaptability: From Consumer Electronics to Industrial Equipment

The GBLC03C’s applications are far-reaching. In consumer electronics such as cell phone handsets and accessories, laptops, and USB interfaces, it serves as an "invisible guardian" ensuring signal stability. In industrial settings like microprocessor-based equipment and portable instrumentation, it protects circuit safety with reliable performance. This versatility stems from its SOD-323 miniature package—its compact size facilitates integration into high-density circuit boards, and its tolerance for high-temperature soldering (260℃/10s) makes it ideal for mass production.

Why Choose the GBLC03C?

For circuit designs prioritizing low power consumption and high signal integrity, its advantages are clear: ultra-low capacitance reduces signal attenuation, low leakage current cuts energy consumption, and stringent protection standards translate to longer device lifespans. Through this "subtle yet effective" protective design, Slkor has made the GBLC03C a trusted choice from laboratory to production line.
