STMicroelectronics USBULC6-3F3 USB Transil™ Protection Device
The USBULC6-3F3 from STMicroelectronics is a high-quality, robust Transil™ protection device designed specifically for the safeguarding of sensitive USB interface lines against electrostatic discharge (ESD), electrical fast transients (EFT), and other harmful voltage-induced transient phenomena. This device is an ideal solution for applications that require reliable protection for one USB data line or two lines of a USB power delivery (PD) interface.
Featuring a low capacitance bi-directional TVS diode, the USBULC6-3F3 ensures minimal signal distortion while providing a strong defensive barrier against transient voltages. The device is capable of withstanding ESD up to 15 kV and is compliant with the IEC 61000-4-2 standard, making it a perfect fit for protecting high-speed data lines that are susceptible to ESD events.
The compact SOT-23-6L package of the USBULC6-3F3 allows for space-saving on PCB layouts, which is particularly advantageous in portable electronic devices where board space is at a premium. This small footprint does not compromise its protective capabilities, as it can absorb repetitive ESD strikes at the maximum level specified in the IEC 61000-4-2 international standard without performance degradation.
With a break-down voltage of 6 V and a maximum clamping voltage of 15 V, the USBULC6-3F3 is capable of protecting sensitive components connected to the USB ports against both ESD and surge transients. The device's low leakage current ensures that it does not significantly affect the battery life of portable applications.
Applications for the USBULC6-3F3 include a wide range of consumer electronics such as smartphones, digital cameras, and MP3 players, as well as peripherals like printers and external hard drives. It is also suitable for use in telecommunication systems and industrial control interfaces where USB connections are commonly used.
In summary, the USBULC6-3F3 is a high-performance, space-efficient protection solution from STMicroelectronics that offers robust protection for USB data and power lines, ensuring the longevity and reliability of your electronic devices.
