Notes on technology and VCE(sat) grouping

An advanced PT IGBT has been introduced to enhance the previous 600 V, 35 A IGBT

STGW35NC60WD, tailored for high-frequency applications. From a technology point of

view, two main improvements have been implemented on this IGBT:

The innovative double-drift process which changed the doping profile

The advanced planar strip layout

Both factors allow the reduction of the effective resistance in the drift (N ¯) region and

significantly improve the dynamic performance, especially at high temperature. The

changes performed on the horizontal and vertical structure and their effect on this IGBT are

clearly shown in its datasheet: the new STGW35HF60WD shows a lower VCE(sat) typical

value than the equivalent STGW35NC60WD, and its Eoff max value (at IC = 20 A,

TJ = 125 °C) is guaranteed as per the datasheet. Tests performed on a significant number of

STGW35HF60WD samples show that the static temperature coefficient (see Equation 2),

changes in relation to the absolute VCE(sat) value, as shown in Figure 3.

Figure 3 also explains how the total VCE(sat) population has been split to guarantee well-

balanced and reliable paralleling. The

∆ symbol beside group A, whose VCE(sat) values

belong to the interval (1.68 V

− 1.92 V [@20 A, 25 °C]), satisfies the equation:
