Key Features
Superior ESD Protection Performance: Compliant with the IEC 61000-4-2 standard, it can withstand ±15kV contact discharge and ±25kV air discharge. This effectively resists electrostatic shocks to USB interface circuits, protecting the core chips of devices adapted with USBLC6-2SC6.
Compact SC6 Package Design: Adopting an ultra-small SC6 package (size approximately 1.6mm×0.8mm), it significantly saves PCB board space, meets the demand for miniaturized components in portable electronic devices, and improves the compatibility of USBLC6-2SC6 in high-density circuit boards.
Low Clamping Voltage Characteristic: When ESD occurs, the clamping voltage of USBLC6-2SC6 is as low as 7.5V (typical value), which can quickly limit the overvoltage to a safe range and prevent damage to backend sensitive components (such as USB controllers) due to overvoltage.
Wide Operating Voltage Range: With a rated working voltage (Vrwm) of 3.3V, it is compatible with the low-voltage power supply requirements of USB interfaces. Meanwhile, it supports a wide operating temperature range of -40℃~+85℃, ensuring stable operation of USBLC6-2SC6 in harsh environments.
Full USB Standard Compatibility: Perfectly compatible with mainstream USB interface protocols such as USB 2.0, USB 3.x, and USB Type-C, it can be integrated without additional circuit adjustments, reducing the application development cost of USBLC6-2SC6.

Typical Applications
USB Type-C Mobile Devices: In devices equipped with USB Type-C interfaces such as smartphones, tablets, and wireless earbuds, USBLC6-2SC6 can be integrated into the charging/data interface circuit to resist static electricity generated during user plugging and unplugging, preventing interface failure or motherboard damage, and ensuring the stability of device charging and data transmission.
Portable Computers and Accessories: For laptops, ultrabooks, and USB hubs, USBLC6-2SC6 can provide unified ESD protection for multiple USB ports. Especially in scenarios where USB flash drives and external hard drives are frequently plugged and unplugged, it effectively reduces the risk of interface failures caused by static electricity and extends the service life of devices.
Consumer Electronic Devices: In devices such as digital cameras, action cameras, and portable speakers, USBLC6-2SC6 meets the miniaturization design needs of the devices. It saves internal space through the SC6 package while providing reliable protection for USB charging interfaces, adapting to the electrostatic environment in daily use.
Industrial Control Equipment: In industrial scenarios, USB interfaces are often used for data transmission of sensors, PLC programmers, human-machine interfaces (HMI), etc. The wide operating temperature range (-40℃~+85℃) of USBLC6-2SC6 can adapt to the high and low temperature environments of factory workshops, avoiding misoperation or data loss of industrial equipment caused by electrostatic interference.
Automotive Electronic Systems: In in-vehicle USB charging interfaces and car infotainment data interfaces, USBLC6-2SC6 can resist electrostatic shocks during car operation (such as static electricity when personnel touch the interface) and tolerate temperature fluctuations in the in-vehicle environment, ensuring the stable operation of the automotive electronic system and improving driving safety and convenience.
Why Choose USBLC6-2SC6 ?
High-Reliability Protection, Reducing Maintenance Costs: The ESD protection level of USBLC6-2SC6 reaches the highest level of IEC 61000-4-2 (±15kV contact discharge), which can reduce the USB interface static damage rate by more than 90%, lower the after-sales maintenance cost of devices, and improve the product's market reputation.
Miniaturized Package, Adapting to High-Density Design: The SC6 package is 30% smaller in size than the traditional SOT-23 package, allowing more functions to be integrated in limited PCB space. It meets the "thin and light" design trend of current electronic devices and provides engineers with greater flexibility in circuit layout.
Low Clamping Voltage, Protecting Sensitive Chips: The typical clamping voltage of 7.5V is much lower than the voltage tolerance limit of most USB controllers (usually 10V). It can quickly limit the ESD overvoltage to a safe range, avoiding burnout of backend chips and ensuring the long-term stability of the circuit protected by USBLC6-2SC6.
Wide Temperature Adaptation, Strong Scene Compatibility: The operating temperature range of -40℃~+85℃ covers most scenarios from cold regions to high-temperature industrial environments. There is no need to adjust the protection scheme for different environments, which lowers the application threshold of USBLC6-2SC6 and is suitable for product development in multiple fields.
Industry Standard Compatibility, High Development Efficiency: USBLC6-2SC6 complies with the interface protection requirements of the USB-IF association and is seamlessly compatible with mainstream USB protocols (USB 2.0/3.x/Type-C). Engineers can directly replace traditional protection devices without redesigning the circuit, shortening the product development cycle.
