ProTek Devices’ Intros TVS Array to Thwart Malicious and Accidental USB Killer Attacks

DFN-14 package of ProTek device-TVS array

ProTek Equipment Corporation introduced the TVS array, which is capable of defending against malicious or unsuspecting USB Killer attacks, which has proven to be costly for organizations in terms of equipment and data loss. The new components provide circuit protection to prevent positive ESD on data lines, fast surge voltage transients and high negative voltage transients, such as the protection that USB Killer devices can achieve.

After the USB Killer is inserted into the USB port, it may immediately destroy the connected device and threaten other connected devices. USB killer

Malicious destruction of equipment. However, when people mistake them for universal USB memory sticks, they can also be an unquestionable threat. The PRUSB05UBK component of ProTek equipment is specifically designed to stop this type of threat.

The new steering diode/transient voltage suppressor array (TVS array) is very suitable for dual USB 2.0 ports, USB 1.0 and power bus. It is also suitable for circuit protection of Gigabit Ethernet ports, portable electronic devices, video card interfaces and DVI interfaces.

PRUSB05UBK has an ultra-low capacitance CJ (SD) of 2.5pF. The typical value is an integrated resistor on each data line. It complies with the IEC industrial standard 61000-4-2 (ESD): air ±15kV, contact ±8kV; 61000-4-4 (EFT): 40A, 5 / 50ns; and has 61000-4-5 (surge): 24A , 8/20 microseconds-level 2 (LineGnd) and level 3 (line-line).

It provides protection for four lines, each line provides 500 watts of peak pulse power (typical value = 8/20 microseconds). The rated voltage of ESD protection is up to 25 kV. The new components also provide a low clamping voltage and comply with RoHS and REACH standards.

Machinery, packaging and inventory information

ProTek Devices’ PRUSB05UBK is packaged in DFN-14 and weighs only 16 mg. Other mechanical and packaging features include lead-free pure tin plating and a solder reflow temperature of 260-270 degrees Celsius (pure tin-Sn, 100). Operating and storage temperature is -55 to 150 degrees Celsius. And, the flammability rating is UL 94V-0.

According to EIA Standard 481, this steering diode/TVS array is available in 16mm tape and reel packaging, with batch sizes starting from 1,000.
