SD Series – Fast Response, Effective Protection

The SD series is a family of protection diodes designed for effective suppression of transient overvoltages and electrostatic discharges (ESD) that may interfere with the operation of modern electronic circuits. The high sensitivity of today’s semiconductor components makes these devices essential for ensuring system reliability. The family includes the SD03, SD03C, SD05C, and SD12C models, which differ in operating voltage and parameters tailored to specific design requirements. Variants marked with the “C” suffix provide additional improvements such as lower input capacitance and optimized clamping voltage. This allows designers to flexibly select the most suitable device for protecting individual circuits while maintaining signal integrity and overall system stability.

Technical parameters:

• Fast response time – immediate reaction to surges, protecting circuits from damage.
• Low signal line capacitance – minimal impact on signal quality and circuit performance.
• Compact package – space-saving on the PCB, easy mounting.
• High reliability and stable operation – proven protection under different environmental conditions.
• Versatile integration – easy to adapt to consumer electronics, telecommunications, and industrial projects.
• Special “C” versions – additional parameters tailored to voltage and design requirements.

Applications:

• Consumer electronics – smartphones, tablets, laptops, audio and video devices requiring protection of sensitive circuits.
• Telecommunications – routers, modems, and networking equipment protected against surges and signal disturbances.
• IoT modules – safeguarding sensors, communication modules, and control circuits in portable devices.
• Industrial systems – controllers, panels, and automation modules requiring protection in demanding environments.
• Power supplies and energy circuits – protection of sensitive components from surges in low-voltage power rails.
• Prototyping and mass production – easy integration in both test projects and serial production devices.
