Schottky Barrier Diodes Guaranteed at 175℃
SLSBD® Series Expansion |
 |
Shindengen Electric Manufacturing Co., Ltd. (headquartered in Otemachi, Chiyoda-ku, Tokyo, Japan) is expanding the lineup of its ＳＬＳＢＤ®series of high-efficiency, low-leakage, heat-resistant Schottky Barrier Diodes (guaranteed up to 175℃).
We have developed a product which is ideal for the automotive market, and November 2008 marks the start of mass-production.
We will continue to expand our lineup of surface-mounting products for the automotive market and to strengthen our sales. |
1．Overview
As consciousness about protecting the earth's environment rises, so do demand and expectations for HEVs (hybrid cars), EVs (electric cars) and the like. As these next-generation cars' power use represents dramatic increase compared to the old gasoline cars, in order to improve fuel efficiency, shrink sizes and lighten weights, demand has grown for circuit technology and device products that can curb loss in power conversion.
So, to answer the needs of the automotive market, we developed the SLSBD®series, usable even in such high-temperature environments as those of engine compartments. It is guaranteed at up to 175℃. And now we have added the product, optimal for use in cars, to the line.
SBDs have long been used in various power circuits as power diodes with high efficiency and low noise. However, concerns over how, under high-temperature environments, reverse current (hereafter ＩＲ） would rise and self-heating would lead to failure (thermal runaway) limited the scope of their utilization despite their outstanding characteristics.
To overcome these SBD shortfalls, we selected wafers, optimized our process structure, employed our own new Schottky barrier formation method, and so developed the SLSBD®series. We succeeded in both maintaining the forward voltage (hereafter VF）characteristic in the tradeoff relationship and lowering the ＩＲ level by one order of magnitude or more compared to our previous product.*1
With the appearance of this SLSBD®series, it is now possible to use high-efficiency SBD in peace even in high-temperature environments like automobile engine compartments.
We shall continue our design and development in pursuit of "environmental performance". We shall continue to supply environmentally friendly, high-performance power devices.
