Back in August, ProTek Devices introduced the PLR3311, a very low capacitance TVS array designed to protect computing applications from the damaging effects of ESD and EFT. Such computing applications include Ethernet 10/100/1000 Base T, FireWire, wireless communications devices and USB interfaces.


ESCS distributes ProTek PLR3311

 

The PLR3311 meets the 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 0603 package is ideal for LCD TVs; digital cameras; DVD and Blu-ray players; camcorders; and game consoles. It’s also ideal for power-over-Ethernet; hard drives; and other consumer devices. The 1206 part numbers are PF1206F, PF1206S and PF1206H. The PF1206F is a fast-acting chip fuse. The PF1206S is a slow-blow chip fuse. And, the PF1206H is a high inrush chip fuse. The 1206 package is ideal for smart phones; DVD and Blu-ray players; game consoles; and digital music players. The 1206 is also ideal for GPS devices; audio systems; switching power supplies and chargers; and scanners. In addition, the 1206 package is well suited for telecom infrastructure equipment and DSL/cable modems.

ESCS now distributes  ProTek SMCJ5.0C and SMCJ36A
The SMCJ5.0C and SMCJ36A feature compatibility with IEC 61000-4-2 (ESD), 61000-4-4 (EFT), and 61000-4-5 (surge). The SMCJ5.0C and SMCJ36A are also glass passivated chips offering 1,500 watts peak pulse power per Line (tp = 10/1000μs). This family consists of five parts with various reverse stand-off voltages. They include the SMCJ5.0C and SMCJ5.0CA at 5.0 volts. The SMCJ5.0C has a maximum breakdown voltage of 7.30 volts while the SMCJ5.0CA is at 7.00 volts. The rated stand-off voltage of the other parts include the SMCJ26A at 26.0 volts; the SMCJ33A at 33.0 volts; and the SMCJ36A at 36.0 volts. All parts provide low leakage current and bidirectional and unidirectional configurations. They also offer excellent clamping capabilities and very fast response times. The parts are all RoHS and REACH compliant. These parts are provided in a molded JEDEC DO-214AB package with an approximate weight of just 0.248 grams. They feature lead-free pure-tin plating (annealed) and a solder reflow temperature (pure-tin – Sn, 100) of 260-270 degrees Celsius. The terminals can be soldered, per MIL-STD-750, method 2026. The TVS components also carry a flammability rating of UL 94V-0. They can be had in 16mm tape and reel, per EIA standard 481.

ProTek Devices increases Surge Test Throughput by 5X

Electronic Supply Chain Solutions is the AS9120 Certified Franchised Distributor for ProTek Devices who Increased Surge Test Throughput by 5X with NI LabVIEW and NI hardware We increased throughput by 5X and reduced costs by 40 percent". says Prashanth Patil, of  ProTek Devices .

The Challenge:                                                                        

increases Surge Test Throughput by 5X

Developing a surge tester to test transient voltage suppressor (TVS) and steering diode arrays using a custom field-programmable gate array (FPGA)-based source measure unit (SMU) to increase throughput by decreasing test time.

The Solution:

Using NI LabVIEW software and the NI LabVIEW FPGA module to develop a custom automated surge tester for a broad range of TVS products.

Automating TVS Product Line Testing
ProTek Devices manufactures TVS and steering diode array products designed specifically to protect electronic systems from the destructive effects of lightning, electrostatic discharge, nuclear electromagnetic pulses, electromagnetic interference, radio-frequency interference, and inductive switching. We also offer application-specific protection solutions for any type of electronic equipment or system.
We needed an automated test solution to test different TVS product lines on the manufacturing floor. The test solution needed to support initial wafer qualifications and product acceptance during product life cycles. The TVS performance measurement system performs fundamental tests such as breakdown voltage, current leakage, forward voltage, surge test, capacitance measure, and other proprietary tests.
We considered many concepts during the equipment design and prototype development phases, and ultimately chose the LabVIEW FPGA Module because it offered the quickest test time and cost advantages. The final test system consists of ProTek proprietary hardware and a desktop computer with an R Series FPGA device installed.

We used LabVIEW to write the host application and LabVIEW FPGA to control the R Series FPGA target. The host program collects user information, controls the host FPGA program, and postprocesses data. Test software development with LabVIEW and operator training time was minimal.

We used an NI R Series multifunction RIO device with an FPGA to control the hardware digital I/O lines, which generate custom surge waveforms using internal FPGA lookup tables. The FPGA device also reads the measured values using its internal A/D converters, stores the data in memory, and controls the external semiconductor handler with custom triggering. The FPGA sets the forcing current or voltage limits in the circuitry to bias the device under test (DUT) and measure back the current through, or voltage across, the DUT. We also developed distribution analysis code, which tracks device performance during production runs, and failure analysis code to assess problem root cause and help us quickly and easily take corrective and preventive action.

The FPGA-based test system can generate 10 different waveforms, including double exponential, half sine, and square waveforms. For comparison, using the previous SMU test system, we could only generate a few waveforms, and each pair of waveforms required a separate printed circuit board (PCB). Now, we generate all 10 required waveforms without using any custom-built PCBs by using built-in FPGA memory while retaining sufficient memory for future additional waveforms.

We replaced the traditional box instrument SMU with custom-built source measure circuitry using LabVIEW and FPGA technology. As a result, we improved voltage, leakage, and surge test times by up to 10X. Furthermore, we compared hardware costs and found that the new system resulted in a 40 percent cost reduction over the previous box instrument solution.

Delivering Increased Production Throughput - Using LabVIEW and an R Series FPGA device, we developed a high-speed surge tester that delivered increased production throughput on the order of 5X. With LabVIEW and FPGA versatility, this custom solution is easy to mass-produce and provides report generation, failure analysis, and a sophisticated user interface.
