LESD05V32D-LC: Ultra-Compact SOD-323 ESD Protection for High-Speed, Low-Voltage Interfaces

 Slkor has unveiled the SLESD05V32D-LC ESD protection diode, engineered to overcome space limitations with its ultra-compact SOD-323 package. Purpose-built for 5V low-voltage, high-speed circuit applications, it delivers efficient suppression of electrostatic discharge (ESD) and electrical fast transient (EFT) events. Acting as a “micro protective shield,” it safeguards sensitive circuits in mobile phone camera modules, USB Type-C interfaces, and laptops, effectively resolving the long-standing trade-off between ultra-miniaturized design and high-level protection performance.

Micro Package + Precise Protection, Adaptable to High-Density Circuits

The SLESD05V32D-LC redefines space efficiency in circuit protection with its ultra-compact SOD-323 package. Its terminals feature gold-plated technology and comply with MIL-STD-750 solderability standards, ensuring high reliability on automated production lines. Supplied in 7-inch tape-and-reel packaging (3,000 units per reel) and manufactured with halogen-free materials, it aligns with global environmental requirements and integrates seamlessly into millimeter-level PCB layouts for smartphones, wearables, and other space-constrained designs.

In terms of electrical performance, the device is precisely tuned for 5V low-voltage systems:
 ● Reverse working voltage (V₍RWM₎) of 5.0V, ideally matched to consumer electronics and portable devices, maintaining a high-impedance state under normal operation with zero signal disturbance;
 ● Static leakage current (I₍R₎) ≤1μA, minimizing standby power consumption and extending battery life;
 ● Junction capacitance (C₍J₎) ≤15pF (V₍R₎=0V, f=1MHz), enabling near “zero-loss” performance for high-speed signals such as USB 2.0 and UART, preserving data integrity;

● Protection performance compliant with IEC 61000–4–2: ±15kV air discharge, ±8kV contact discharge, and the ability to clamp 40A (5/50ns) transient currents within 16V, providing robust defense against ESD during plug-in/out events and electromagnetic pulse shocks.

Covering Multiple Scenarios, Solving the Challenge of “Limited Space + High Protection”
 From key consumer electronics modules (mobile phone cameras, Type-C interfaces, Bluetooth modules) to portable devices (tablets, smartwatches) and low-voltage industrial control circuits, the SLESD05V32D-LC stands out as a preferred solution for space-limited applications through its unique combination of miniaturization and strong protection:
 ● In wearable devices, its millimeter-scale footprint frees valuable PCB area for sensors and wireless modules while effectively resisting human-body ESD;
 ● In high-speed interfaces (USB, HDMI), the low junction capacitance preserves signal integrity, while the 1μA leakage current eliminates unnecessary standby power loss;
 ● In industrial control applications, the 5V-rated design ensures compatibility with low-voltage sensors, and the 100W peak pulse power (8/20μs) provides reliable suppression of electromagnetic transients.

Behind the Technological Breakthrough: Targeting the “Miniaturization + High Performance” Trend
 “The core innovation of the SLESD05V32D-LC lies in the deep integration of ultra-low capacitance, ultra-low leakage current, and micro-scale packaging,” said the head of Slkor’s protection device product line. “As consumer electronics continue to evolve toward being thinner, lighter, and smarter, we have optimized electrical performance and packaging in parallel. This transforms protection devices from mere ‘functional components’ into true ‘design enablers’ — preserving high-speed signal integrity while freeing up valuable millimeter-level PCB space, ultimately empowering next-generation product design.”
