ProTek Devices recently introduced a very low capacitance transient voltage suppressor (TVS) array designed to protect computing applications from the damaging effects of electrostatic discharge (ESD) and electrical fast transients (EFT). Such computing applications include Ethernet 10/100/1000 base T, FireWire, wireless communications devices and USB interfaces.
The TVS array is the PLR3311, which meets IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT) and IEC 61000-4-5 (surge) standards requirements. At higher operating frequencies or faster edge rates, insertion loss and signal integrity are a major circuit protection concern. The PLR3311 is designed to remove these concerns. This device offers very low capacitance (5pF [typical]) and low leakage current. It features 40 watts peak pulse power per line (tp = 8/20 micro amps) and a low clamping voltage. The PLR3311 protects one bidirectional line. The component is provided with a rated 3.3 stand-off voltage. It is RoHS and REACH compliant.
The PLR3311 is provided in a molded JEDEC DFN-2-0402 package. It has an approximate weight of just two milligrams. The package features lead-free pure-tin plating (annealed) and a solder reflow temperature (pure-tin – Sn, 100) of 260-270 degrees Celsius. It has a flammability rating of UL 94V-0. The operating and storage temperature for the PLR3311 is -55 to 150 degrees Celsius. Read more.
PF0603F Series Data Sheet Updated
ProTek Devices has also recently made available an updated data sheet for the PF0603F series of fast acting chip fuses. These devices are designed for circuit protection in consumer electronics, computers and telecommunications equipment and devices. For example, these include DSL/cable modems; smartphones and other handheld devices; laptops, desktops and servers; printers, LCD displays and scanners; DVD players, MP3/4 players and more.
They provide overcurrent protection against elements such as fire or shock. The PF0603F series is available in a rugged ceramic and glass package. These devices have excellent environmental performance.
The parts are compatible with reflow and wave soldering and are RoHS and REACH compliant. They meet a myriad of testing standards: MIL-STD-202 for methods 108A; 103; 106G; 107G; 204D and many more. Get the updated data sheet here.
