ProTek Devices Adds Two Steering Diode / TVS Arrays For Circuit Protection In Telecommunications, Computing And Other Equipment

One Part Also Offers EMI/RFI Protection and the Other Is an Addition to a TVS Array Series

Tempe, AZ (PRWEB) - ProTek Devices has added two steering diode / transient voltage suppressor arrays that provide circuit protection for a wide variety of applications such as, telecommunications interfaces, computing interfaces, video cards, and more. One of the new devices can also be used to guard against electromagnetic interference / radio frequency interference.

The PLR4045 steering diode / TVS array provides ultra-low capacitance of 1.6pF (typical) while delivering circuit protection for critical applications. These applications include 2.5GBASE-T, T1/E1 and T3/E3 chip-side protection, DVI interfaces and USB 2.0 interfaces. It is rated at 600 watts 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). At higher operating frequencies, or faster edge rates, insertion loss and signal integrity are a major concern. This device, in conjunction with passive components integrated into a TVS / filter network, can be used for EMI / RFI protection. ESD protection is > 25 kilovolts. The PLR4045 also offers unidirectional configuration, a low clamping voltage of 20V (max.) at IPPM = 30A and protects four I/O ports and a power supply.

The PSRV2.8-2LC is an addition to the PSRV-2LC series of low-capacitance (1pF typical) steering diode / TVS arrays. It offers a 2.8 rated standoff voltage. The component is ideal for circuit protection in ethernet - 10/100/1000 Base T, USB, handheld electronics, video cards, WAN/LAN and similar equipment. This series is designed to protect two line pair or four data / transmission lines from the effects of ESD and EFT. The series is ideal 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 micro seconds, level 2(LineGnd) and level 3 (Line-Line). It features 300 watts peak pulse power per line (typical = 8/20 micro seconds). It provides two lines of protection and low leakage current of < 1.0 microampere. Other rated standoff voltages in the series include 3.3 and 5. The leakage current for the 3.3V device is less than 1.0 microampere. Both new parts are RoHS and REACH compliant.

Mechanical, Packaging and Availability Information
Both devices are now available. The PLR4045 is provided in a molded JEDEC MSOP-10 package and has an approximate weight of only 24 milligrams. The PSRV2.8-2LC is offered in a molded DFN-6 package and has an approximate weight of just 9 milligrams. With six leads in the PSRV2.8-2LC, it reduces the internal lead inductance for low overshoot voltage during fast front time transient events, such as ESD. For the PSRV2.8-2LC, pins 1-6, pins 2-5 and pins 3-4 must be connected via PCB traces.

Other key mechanical characteristics for both parts include lead-free pure-tin plating (annealed) and a solder reflow temperature of (pure-tin - Sn, 100) 260 to 270 degrees Celsius. Both also have a flammability rating of UL 94V-0. The PLR4045 is delivered on 12mm tape and reel, per EIA standard 481, in minimum quantities of 1,000. The PSRV-2LC series is provided in 8mm tape and reel, also per EIA standard 481, in minimum quantities of 3,000.
