RIVERSIDE, Calif., August 26, 2014 – Bourns, Inc., a leading manufacturer and supplier of electronic components, today introduced its ChipGuard® Automotive MLA Series Varistor ESD Clamp Protectors Model specifically developed to protect sensitive automotive electronics from the threat of ESD up to IEC 61000-4-2 Level 4. Bourns’ Model CGA-MLA Series are very fast bidirectional devices that deliver robust overvoltage protection and stable low leakage performance over a wide temperature range. The latest ChipGuard® devices from Bourns also feature multilayered varistor technology, and their proprietary insulating overcoat provides low and stable leakage current, quick response time (<0.5 ns) and high transient current capability. These features and benefits make the new varistor clamp protectors particularly well-suited to meet the ESD protection needs of HDMI, CANbus, Ethernet, sensor and touchscreen interfaces as well as GPS and camera links and other circuits sensitive to ESD.

“Like our automotive industry customers, Bourns takes adherence to standards very seriously. That is why these new devices are AEC-Q200-qualified and also meet the IEC 61000-4-2 standard,” said Kurt Wattelet, Product Line Manager at Bourns, Inc. “High performance and reliability make Bourns’ new varistor series an excellent electrical protection solution for sunroofs and control units as well as engine management systems, just to name a few.”

Pricing and Availability

The new models are AEC-Q200 and RoHS compliant*. Bourns® Model CGA-MLA Series is available now in 0603, 0805 and 1206 type packages. As a pricing reference, CGA0603 modes are priced at $.10 each in 10,000 piece quantities. For more information, please see the www.bourns.com/data/global/pdfs/CGA-MLA.pdf.

RIVERSIDE, Calif., August 20, 2014 – Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced two new high Power TVS diodes that offer enhanced protection in surface mount SMD packaging. The new diodes are designed for DC clamping in exposed AC/DC power supply applications such as wireless base stations. Designated Models PTVS3-058C-SH and PTVS3-076C-SH, the latest high current bidirectional TVS diodes from Bourns offer bidirectional port protection meeting IEC 61000-4-5 8/20 μs current surge requirements.

“Silicon technology in Bourns® Power TVS devices delivers multiple advantages including lower clamping voltage under surge, greater performance stability and increased reliability compared to competing MOV technology that is typically used for DC clamping applications,” said Ben Huang, Product Line Manager at Bourns, Inc. “DC power supplies used in telecom and other exposed applications need protection against hostile events, such as power line surges and indirect lightning strikes to the power supply, by limiting the peak surge voltage to an acceptable level and by not short-circuiting the line for an extended period of time. Bourns® Power TVS diodes are excellent solutions to satisfy these requirements that can help minimize critical system downtime and avoid costly maintenance calls.”

Bourns selected the SMD package for its latest Power TVS products because this type of packaging can simplify assembly and reduce manufacturing costs by eliminating the extra assembly step in situations where the Power TVS diode is the only through-hole component on the printed circuit board. These devices offer excellent surge response versus temperature, where the typical maximum surge current at 150 °C exceeds 70 % of their rated value at 25 °C. The new models also feature standoff voltage of 58 V and 76 V with a peak pulse current rating of 3 kA.

Pricing and Availability
As a pricing reference, the Bourns® Models PTVS3-058C-SH and PTVS3-076C-SH are priced at $23.51 each in 20 piece quantities and $21.70 each in 500 piece quantities. Both new Power TVS diode models are available now and are RoHS compliant*.

Bourns’ application note on surface mount Power TVS diodes has been updated with this new model information, and the product data sheet with detailed specifications is available on the Bourns’ website.
