New steering diode/TVS arrays for circuit protection in telecommunications, computing and other equipment

ProTek Devices has added two steering diode/transient voltage suppressor arrays providing circuit protection for a broad range of applications such as computing interfaces, telecommunications interfaces, video cards, and more. One of the new devices can also be used to guard against radio frequency and electromagnetic interference. The PLR4045 steering diode/TVS array offers ultra-low capacitance of 1.6pF (typical) while producing circuit protection for critical applications. These applications include DVI interfaces, USB 2.0 interfaces, and 2.5GBASE-T, T1/E1 and T3/E3 chip-side protection. It is rated at 600W peak pulse power (8/20 micro seconds waveform). It is compatible with IEC standards 61000-4-2 (ESD): air ±15kV, contact ±8kV; 61000-4-4 (EFT); and 61000-4-5 (surge). The PSRV2.8-2LC is an extention to the PSRV-2LC series of low-capacitance (1pF typical) steering diode/TVS arrays. It provides a 2.8 rated standoff voltage. The component is perfect for circuit protection in ethernet - handheld electronics, video cards, 10/100/1000 Base T, USB, WAN/LAN and similar equipment. This series is developed to protect two line pair or four data/transmission lines from the impacts of ESD and EFT. The series is perfect for low voltage circuit applications, and the low capacitance of the steering diode allows the designer to protect high-speed data applications. This device is compatible with IEC standards 61000-4-2 (ESD): air: ±15kV, contact: ±8kV; 61000-4-4 (EFT): 40A - 5/50ns; and 61000-4-5 (surge): 24A, 8/20 microseconds, level 2(LineGnd) and level 3 (Line-Line). Both new parts are RoHS and REACH compliant.
