RIVERSIDE, Calif., January 28, 2014 – Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced the introduction of new high Power TVS diode models in SMD packaging for use in AC and DC power line applications. The new models feature high current bidirectional port protection meeting IEC 61000-4-5 8/20 µs current surge requirements and are RoHS* compliant. Designated Bourns® Models PTVS15-058C-SH and PTVS15-076C-SH, these Power TVS diodes offer enhanced performance stability and increased reliability. Designed using advanced silicon technology Bourns’ new devices deliver lower clamping voltage under surge compared to Metal Oxide Varistor (MOV) technology. The SMD package provides a 20% reduction in peak clamping voltage compared to an equivalent through-hole device because of its lower lead inductance. The result is reduced electrical stress on the protected circuitry. Additionally, the SMD package simplifies assembly and can reduce costs by eliminating the extra design requirements in cases where the Power TVS diode is the only through-hole component on the printed circuit board.

“Bourns’ Power TVS diodes are becoming increasingly popular because they provide robust circuit protection against power line surges and indirect lightning strikes in AC and DC power supplies used in telecom and other exposed applications,” said Ben Huang, Semiconductor Product Line Manager at Bourns, Inc. “We designed these new models with specific packaging technology giving our customers the benefit of a highly reliable solution that meets the growing protection demands of today’s high power applications.”

Bourns’ new Power TVS diode models also exhibit an excellent surge response versus temperature, with a maximum surge current rating at 150 °C, which is 70% of their rated value at 25 °C. Both models provide very high surge current protection with a peak pulse current rating of 15 kA. The Bourns® Model PTVS15-058C-SH features a 58 V standoff voltage and the Bourns® model PTVS15-076C-SH has a 76 V standoff voltage.

Pricing and Availability
As a pricing reference, the Bourns® models PTVS15-058C-SH and PTVS15-076C-SH are priced at $19.70 each in 10 piece quantities and $17.50 each in 500 piece quantities respectively. Both models are available now. For additional product specifications, please go to: www.bourns.com/data/global/pdfs/PTVS15-SH.pdf.

Bourns First to Develop Simplified One-Page Documentation Series on Port Interface Circuit Protection

June 15, 2010

Bourns® PortNote™ Solutions & Design Kits

RIVERSIDE, Calif., June 15, 2010 – Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced the introduction of a unique new series of useful design documentation developed to assist designers in selecting the appropriate circuit protection solution for a specific port interface. Bourns® PortNote™ Solutions are a series of one-page documents that provide concise and easily understandable information on relevant compliance standards, Bourns solutions and part numbers, the specific interface schematic and alternative solution references. As the majority of circuit protection products are designed into variations of just a few ports, each Bourns® PortNote™ Solution offers designers a simple starting point for the protection of a particular port.

“Bourns® PortNote™ Solutions are a time-saving design tool that quickly provides an effective circuit protection solution known to work in most typical applications down to the Bourns® part number,” said Dr. Erik Meijer, vice president of circuit protection at Bourns. “PortNote™ Solutions are not intended to replace detailed application notes or the customized solutions provided by our FAE teams, but rather be a useful resource to streamline the circuit protection selection process for a specific port interface.”

Accessible on the Bourns website, Bourns currently has 13 PortNote™ Solutions in its documentation library with more in development and planned for release in the near future. At present, there are four PortNote™ Solutions that cover Ethernet and USB ports for datacom applications; three on HDMI and VHF/UHF coaxial ports for audio/video applications and six show solutions for ISDN, various RJ11 and VDSL ports in telecom designs.  In addition, Bourns offers corresponding Design Kits. Each design kit contains enough Bourns® products to build five of the circuits suggested in the PortNote™ Solution. To view the individual Bourns® PortNote™ Solutions or to inquire about the design kits, go to the Bourns website at http://www.bourns.com/Library.aspx?name=PortNoteSolutions.
