Diodes Incorporated Introduces PowerDI®5 Bipolars that Bring Big Space Savings

Size and Thermal Advantages of PowerDI®5 Package Produce Space Saving Alternative to
Much Larger SOT223 and DPAK (TO252) Products

Dallas, Texas - Diodes Incorporated (Nasdaq: DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete and analog semiconductor markets, today announced its first transistor products in its miniature PowerDI®5 surface mount package. Designed on the Company's industry-leading 5th generation matrix emitter process, a range of 12 NPN and PNP transistors has initially been released, helping designers to significantly raise power densities and shrink solution size.

With a footprint of just 26mm², PowerDI®5 occupies 47% less space than SOT223 and 60%
less space than DPAK. In terms of off-board height, PowerDI®5's 1.1mm compares
favorably with SOT223's 1.65mm and DPAK's 2.3mm.

PowerDI®5's minimum copper power rating of 0.74W means that it delivers excellent
thermal performance from a small area to dramatically improve power density. Its thermal resistance rating of 75ºC/W on 25mm x 25mm copper and FR4 gives a power rating of 1.7W, enabling it to replace SOT223 in applications that rely on package thermal

The first NPN and PNP bipolar products in the new PowerDI®5 package are aimed at
datacom, telecom, motor drive and battery charger applications.

In 100V, 140V and 200V ratings, with low saturation voltage and fast switching
characteristics, the DXT2013P5, DXT2014P5 and DXTP03200BP5 achieve good efficiency
improvements in SLIC DC-DC converters. In linear battery chargers, the low saturation
voltage of the 20-volt DXTP19020DP5 ensures battery charging to full capacity even at a
low charger input voltage.

The package's small size and low thermal resistance makes the 100V rated DXTN07100BP5
device well suited for 48V regulator applications, and the DXT5551P5 as a telecom line
driver when higher voltages are needed to accommodate long line length.
