PLR2512 – PLR3312
There’s a revised data sheet for ProTek Devices’ PLR2512 – PLR3312 ultra-low capacitance (3pF typical) transient voltage suppressor arrays. The components are ideal for circuit protection in high speed applications that include: Gigabit Ethernet, integrated magnetics/RJ-45 connectors, LAN/WAN equipment, security cameras, industrial controls, notebooks and desktop computers, and more.
These TVS arrays are compatible with IEC 61000-4-2 (ESD): Air 15kV, Contact 8kV and with 61000-4-4 (EFT): 40A, 5/50ns. They offer 100 watts peak pulse power per line, (tp = 8/20 micro seconds) and ESD protection of > 25 kilovolts. They protect two line pairs and also boast low leakage current of 10nA. In addition, they provide a low stand-off voltage of either 2.5V or 3.3V. The parts are also RoHS and REACH compliant.
ProTek Devices’ PLR2512 – PLR3312 are provided in a molded DFN-8 package which minimizes lead inductance to prevent overshoot voltages during high ESD current events. The components have an approximate weight of just seven milligrams. Other key mechanical features include lead-free nickel paladium gold plating, a solder reflow temperature of 260 to 270 degrees Celsius, and a flammability rating of UL 94V-0. The parts can be had in 8mm tape and reel per EIA standard 481. The revised data sheet can be had here.
SM3KW08A – SM3KW24A
The SM3KWxxA series also recently saw updates to the data sheet. These TVS parts are high-powered surface mount transient voltage suppression components designed to protect equipment and systems from the damaging effects of high voltage spikes. Such applications include relay drives, motor (start/stop) back EMF protection, module lightning protection, and secondary lightning protection.
ProTek Devices’ SM3KWxxA series boasts IEC compatibility with 61000-4-5 (surge): 48A, 8/20 micro seconds – L3 (line-ground), L4 (line-line) and L1 (power). The series provides 3,000 watts peak pulse power per line (tp = 10/1000 micro seconds), unidirectional configuration, and easy mounting to a printed circuit board. The series is also RoHS and REACH compliant.
Mechanical details include an approximate weight of only 2.5 grams and lead-free silver plating. The SM3KWxxA series has a solder reflow temperature of 260 to 270 degrees Celsius and a flammability rating of UL 94V-0. The DFN-2-3KW surface mount package configuration provides a lower profile at a reduced cost. The series is available in 12mm tape and reel per EIA standard 481. The revised data sheet is available here.
