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.

RIVERSIDE, Calif., March 24, 2010 — Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced the introduction of four new ESD/EFT/Surge Protection series products designed to meet the space-constrained needs of portable communications, computing and video applications. The new transient voltage suppressor (TVS) diodes offer optimal protection for surge and ESD threats and are available in industry standard SMT package size formats. The new RoHS compliant* diodes comply with IEC 61000-4-2 ESD (Min. Level 4), IEC 61000-4-4 EFT, and IEC 61000-4-5 Surge industry standards. Bourns® chip diodes provide ease of manufacturability with standard pick and place equipment and the flat configuration minimizes roll away.

“Bourns designed its new series of discrete TVS diode products in response to growing customer demand for smaller components in a broad range of telecom, consumer, industrial, medical, audio and instrumentation applications,” said Ian Doyle, ESD protection product manager for Bourns. “Our new TVS diodes provide a good circuit protection solution for these applications while also meeting the highest industry standards.”

The new transient voltage suppressor diodes offer a choice of working peak reverse voltage from 5 Volts (V) up to 170 V and breakdown voltage up to 200 V. Below are additional details regarding the Bourns TVS diodes.

Diode Series Details

Series Standoff Voltage (V) Type of Package Power Wattage (W)
SMAJ 5.0-170 Surface Mount SMA 400

Bourns Announces Circuit Protection Solution for Generator Low-Voltage Control Interfaces

March 4, 2010

Bourns® Circuit Protection Products (Download Hi-Res Image)

RIVERSIDE, Calif., March 3, 2010 — Bourns, Inc. today announced the company has a circuit protection solution for low-voltage control lines on generator interfaces.  This advanced solution is presented in a new application note from Bourns that details how the company’s circuit protection devices provide a fast response time to protect exposed low-voltage generator terminals of the generator.  This universal circuit protection solution is also important in delivering adequate circuit protection, regardless of installer experience, to guard against miswiring issues that can result in costly, dead on arrival (DOA) equipment failure.  The new application note includes installation information for both line voltage (120 VAC split phase, 240 V) and low voltage signals (less than 50 V) that require a resettable overcurrent/overvoltage solution capable of handling line voltage and ESD/EFT/current surge protection to safeguard sensitive circuits.

The application note shows how a Bourns® TBU™ device combined with a multilayer oxide varistor (MOV) and zener diode provides power cross and overcurrent protection.  It also describes the use of a zener diode for low voltage clamping to protect sensitive circuits and to create an avalanche current, which triggers the TBU device.  Furthermore, the MOV protects the TBU device from excessive common mode voltages when exposed to ESD and EFT surge threats.

Bourns® TBU devices protect low-voltage generators from the following threats:

  • Power cross events that typically occur during installation from miswiring
  • Pre and post-installation ESD threats from handling EFT and  inductive load (relay) switching
  • Post-installation current surges from load switching transients
