July 23, 2025

Slkor has released the SLESD05V32D-LC electrostatic discharge protector, which breaks through space constraints with an ultra-compact SOD-323 package. Optimized for 5V low-voltage high-speed circuit scenarios, it efficiently resists interference such as electrostatic discharge (ESD) and electrical fast transients (EFT), building a "micro protective shield" for sensitive circuits in devices like mobile phone cameras, Type-C interfaces, and laptops, thus solving the integration contradiction between small-size design and high protection performance.

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

The SLESD05V32D-LC breaks the space limitations of traditional protection devices with its ultra-small SOD-323 package: its terminals adopt gold-plated technology, complying with MIL-STD-750 solderability standards to ensure welding reliability in automated production lines; the 7-inch tape and reel design (3,000 units per reel) is compatible with mass production, and the halogen-free material meets environmental protection trends, easily integrating into "millimeter-level" circuit board layouts of mobile phones, wearable devices, and other products.

In terms of electrical performance, the device is precisely calibrated for 5V low-voltage systems:

● Reverse working voltage (V₍RWM₎) of 5.0V, perfectly matching the power supply requirements of consumer electronics and portable devices, maintaining a high-impedance state under normal conditions without signal interference;

● Static leakage current (I₍R₎) ≤1μA, minimizing standby power consumption and extending battery life;

● Junction capacitance (C₍J₎) ≤15pF (V₍R₎=0V, f=1MHz), achieving "zero loss" for high-speed signals such as USB2.0 and UART, ensuring the integrity of data transmission;

● Protection level meets IEC 61000-4-2 standards: air discharge of ±15kV, contact discharge of ±8kV, and 40A (5/50ns) transient current can be clamped within 16V, easily handling electrostatic discharge from plugging/unplugging and electromagnetic pulse shocks.


Covering Multiple Scenarios, Solving the Pain Point of "Small Space + High Protection"

From core modules of consumer electronics (mobile phone cameras, Type-C interfaces, Bluetooth modules) to portable devices (tablets, smart watches) and low-voltage circuits in industrial control, the SLESD05V32D-LC, with its "miniaturization + strong protection" features, has become the first choice for space-constrained scenarios:

● In wearable devices, the millimeter-level package frees up design space for sensors and wireless modules while resisting human electrostatic interference;

● In high-speed interfaces (USB, HDMI), low junction capacitance ensures signal integrity, and 1μA leakage current avoids "standby power consumption";

● In industrial control, the 5V adaptive voltage is compatible with low-voltage sensors, and the 100W peak pulse power (8/20μs) resists electromagnetic transients.


Behind the Technological Breakthrough: Targeting the "Miniaturization + High Performance" Trend

"The core breakthrough of the SLESD05V32D-LC lies in the deep integration of low capacitance, low leakage current, and micro packaging," said the person in charge of Slkor's protection device product line. "Consumer electronics are evolving towards 'thinner, lighter, and smarter'. Through the collaborative optimization of electrical parameters and packaging, we have turned protection devices from 'functional components' into 'design enablers' — ensuring high-speed signals are undamaged while saving millimeter-level space for circuits, promoting terminal devices to break through design boundaries."
