Application Hints

IMPORTANT INFORMATION

This data sheet contains only product-specific data. All data that apply to

the whole type series of SCALE drivers is given in the document entitled:

“Description and Application Manual for SCALE Drivers”. In particular, this

manual contains a detailed description of the concept of the SCALE

drivers, a description of the function of all terminal pins as well as other

important application hints.

Overview and application

The SCALE driver 2SD106AI is a two channel-driver for power MOSFETs and IGBTs.

Its compact mechanical dimensions and simple electrical interface make this driver

suitable for almost all conceivable applications. When used as a half-bridge driver, the

2SD106AI can directly generate any dead times that may be required.

Output power and self-heating

The specified output power of the driver totals 2W (1W per channel). This typically

suffices to drive a 100A/1200V six-pack IGBT module with 25kHz. In the case of a drive

power of 2W, the typical input power of the driver is about 2.33W; the losses due to

the driver total about 0.33W. Because CONCEPT cannot predict how the drivers will be

incorporated in the user’s application, no binding recommended value for self-heating

and thus for the maximum useful output power at high ambient temperatures can be

made. It is consequently recommended to check the self-heating of the system,

especially when it is used at higher temperatures.

For the calculation of the exact output power, reference should be made to Application
