Summary of First-Half 2018 ProTek Devices’ Product Announcements

Here is a quick summary of the products ProTek Devices has so far introduced in 2018.

PLR4045 & PSRV2.8-2LC

In February, we 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. 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. Read more.

PLR2504

In March, we introduced a new ultra-low capacitance (4pF) steering diode / TVS array for circuit protection in various networking applications. Networking application coverage includes Gigabit Ethernet, T1/E1 and T3/E3 (chip-side), and wireless communications. The new device is also suited for USB and DVI interfaces. This steering diode / TVS array, the PLR2504, provides unidirectional configuration and is rated at 300 watts peak pulse current (8/20 micro seconds wave shape). ESD protection is > 25 kilovolts and the component also provides a very low clamping voltage (VC max 12V @ 25A, 8/20 micro seconds). It protects four I/O ports and a power supply. The PLR2504 is compatible with IEC standards 61000-4-2 (ESD): air ±15kV, contact ±8kV; with 61000-4-4 (EFT): 40A – 5/50ns; and with 61000-4-5 (surge).  And, it is RoHS and REACH compliant. Also, 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 in this scenario. The PLR2504 is now available and is provided in a molded JEDEC DFN-10 package with an approximate weight of only seven milligrams. Read more.

GBLCxxCIDFN Series

Also in March, we introduced a new series of ultra-low capacitance (0.6pF typical) TVS arrays for overvoltage circuit protection in smartphones and other portable electronics. The new series is also suited for Ethernet, USB interface and wireless systems. The GBLCxxCIDFN series of TVS arrays are available in a bidirectional configuration. They are rated at 250 watts peak pulse power per line for an 8/20 micro second waveshape. It is available in multiple voltages. It protects one power or I/O port. ESD protection is > 25kV and the series also offers a low clamping voltage. The new TVS arrays are compatible with IEC requirements for 61000-4-2 (ESD): air – 15kV, contact – 8kV. For this requirement, it exceeds level 4: handles 10kV contact and 25kV air discharge. The GBLCxxCIDFN series is also compatible with IEC 61000-4-4 (EFT): 40A – 5/50ns. The new components are ideal to use as replacements for MLV (0805) devices. In addition, the series is RoHS and REACH compliant. Operating and storage temperatures range from -55 to 150 degrees Celsius. The patent-pending GBLCxxCIDFN series is now available and is provided in a molded JEDEC DFN-2 package with an approximate weight of only 0.8 milligrams. Read more.

The two new parts, in conjunction with passive components integrated into a TVS / filter network, can also be used for electromagnetic / radio frequency interference protection. The new components are the PLR0504PLCN, with a 5.0 volt rated standoff voltage, and the PLR3304PLCN, with a 3.3 volt rated standoff voltage. Other suitable applications include DVI interfaces, high-speed data line ESD protection, FireWire, SATA and PCIe interfaces, and IEEE 1394 to 3.2Gbps. The new TVS arrays provide ultra-low capacitance of 1.5pF max (I/O to GND) and 1.37pF typical for 0Vdc. They are rated at 250 Watts peak pulse power per line for an 8/20 micro second waveshape.  Both components meet or exceed IEC standards requirements for 61000-4-2 (ESD), 61000-4-4 (EFT) and 61000-4-5 (surge). ESD protection is > 25 kilovolts and low-leakage current is < 0.5 microampere. They protect four lines and are also RoHS and REACH compliant. The parts also have a flammability rating of UL 94V-0. The PLR0504PLCN and PLR3304PLCN TVS arrays are now available and are provided in a molded DFN-10 package with an approximate weight of only seven milligrams. Read more.
