New TVS array for high-resolution display and USB circuit protection

ProTek Devices has launched a new steering diode transient voltage suppressor array for circuit protection over popular consumer electronic display interfaces. The new PUSB403 device is perfect for USB 1.0, 2.0, 3.0 and 3.1 and HDMI 1.4 and 2.0 on UHD, and 4K displays.

The new device provides an ultra-low capacitance of 0.15pF typical for I/O-I/O and 0.45pF typical for I/O-GND. The company's PUSB403 also satisfies IEC standards 61000-4-2 (ESD): air ±16kV, contact ±16kV; and 61000-4-4 (EFT); as well as 61000-4-5 (lightning).

The device protects up to four lines and gives low leakage current of <100nA. Additionally, at higher operating frequencies or faster edge rates, insertion loss and signal integrity are a significant concern. This device, together with passive components integrated into a TVS/filter network, can be used for EMI/RFI protection. The PUSB403 is also RoHS and REACH compliant.

Operating and storage temperature is rated at -40C to 85C. Peak pulse current, at 8/20ms, is 6A. Other typical applications benefitting from the device's features can include Gigabit Ethernet, DVI and telecommunications equipment interfaces.
