QSBT40 Offers Significant Space, Reliability and

Cost Advantages Over Monolithic Arrays

Diodes Inc. (Nasdaq:DIOD), a leading manufacturer and supplier of high-quality discrete semiconductors, primarily to the communications, computing, industrial, consumer electronics and automotive industries, today announced the launch of a new quad data line Schottky bus terminator.

The QSBT40 is an innovative high-density array designed to protect the sensitive in/out ports of Time To Live (TTL) and Complementary Metal-Oxide Semiconductor (CMOS) integrated circuits from over voltages caused by induced electrical transients in accordance with IEC 1000-4-2/4/5. End applications standing to gain from improved protection include LAN/WAN equipment, set-top boxes, Ethernet connections and T1 Line cards.

The QSBT40 is also designed to provide bus termination with low capacitance for high-speed parallel data systems such as hard disk drives, DAT drives, disc arrays and network peripherals. The low capacitance device appears virtually transparent to the data signal, but is capable of effectively dissipating an over or under voltage to the VCC or ground rail during a voltage transient or a pulse reflection.

This SOT363 device is based on Diodes' unique Application Specific Multi-Chip Circuit ASMCC high-density implementation. A total of four data line terminators are mounted in one SOT363 surface mount package, with eight separate diodes arranged in four series-connected pairs. This compact 4-line array approach allows for a more effective and efficient layout distribution compared to traditional multi-line monolithic arrays.

In addition, the packaging offers as much as a 10:1 board space reduction ratio compared to other discrete Schottky diodes, with a corresponding reduction in component placement costs.

C.H. Chen, CEO of Diodes, said: "This new device signifies an exciting new phase in our continuing drive to position Diodes Incorporated as a technology leader for discrete devices. We continue to apply our high-density array packaging technology to deliver tangible performance, size and cost benefits to our customers.

"Initial customer reception in the area of high-speed data systems is very strong. We are determined to push the envelope in discrete design technology and introduce higher margin, must-have product lines and extend Diodes' competitive edge."

Pricing and Availability

Samples of the QSBT40 are available now in a 6-pin SOT363 package, through Diodes' network of worldwide representatives and distributors. Lead times on production quantities are stock to four weeks. The device is priced at $0.50 in 10,000-piece quantities, in standard tape and reel packaging.
