ProTek Devices has updated its data sheets for the PLR0508 steering diode / transient voltage suppressor (TVS) array and the SFC05-4 flip chip TVS array for circuit protection.
The PLR0508is an ultra-low capacitance (1.6pF [I/O to I/O]) steering diode / TVS array. This device is designed to protect computing applications such as Gigabit Ethernet; HDMI, DVI and USB interfaces; FireWire, SATA and PCIe interfaces; and high-speed data lines and telecommunications equipment and systems. It provides surge protection from electrostatic discharge (ESD) and electrical fast transients (EFT).
The PLR0508 is available in the space-saving DFN-10 package configuration and is rated at 200 Watts peak pulse current (8/20μs waveshape). This device meets the IEC 61000-4-2 (ESD), 61000-4-4 (EFT) and 61000-4-5 (surge) requirements. 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 PLR0508 offers low clamping voltage and unidirectional configuration. It protects eight I/O ports, a power supply or eight lines. It is RoHS and REACH compliant.
The package is a molded JEDEC DFN-10 package with an approximate weight of just seven milligrams. It 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. It is offered in 12mm tape and reel per EIA standard 481. Download the full data sheet here.
The SFC05-4 is a five volt, flip chip TVS array designed to provide circuit protection for power bus, data, control or I/O lines. Popular applications would include smartphones and cell phones, PCMCIA cards and GPS systems. Rated at 300 watts peak pulse power for an 8/20μs waveshape, this device protects four unidirectional lines. This device is a type of chip scale package (CSP) that can be mounted onto a printed circuit board or in a connector requiring a limited amount of space and is compatible with “pick and place” equipment for automatic assembly. The SFC05-4 is compatible with IEC 61000-4-2 (ESD), 61000-4-4 (EFT) and 61000-4-5 (surge) requirements. ESD protection is > 25 kilovolts. The SFC05-4 is RoHS and REACH compliant.
The quad flip chip package helps to make for an approximate weight of just 0.73 milligrams. The package features lead-free plating and a solder reflow temperature (lead-free – Sn/Ag/Cu, 96/3.5/0.5) of 260-270 degrees Celsius. The top Contacts have a solder bump of 0.004” in height (nominal). The SFC05-4 has a flammability rating of UL 94V-0. It is offered in 8mm tape per EIA standard 481.
