1.

The max ET is calculated to limit the core loss and temperature rise at 100KHz based

on a bipolar flux swing of 180mT Peak. The applied ET may need to be derated for

higher frequencies based on the temperature rise which results from the core and

copper losses.

2.

The temperature rise of the component is calculated based on the total core loss and

copper loss:

A. To calculate total copper loss (W), use the following formula:

Copper Loss (W) = Irms2 * (DCR_Drive + (# of Gates) * DCR_Gates)

B. To calculate total core loss (W), use the following formula:

Core Loss (W) = 6.5E-10*(Frequency in kHz)1.67*(180 * [ET/ET Max])2.53

Where ET is the applied Volt Second, ET Max is the rated Volt Second for 180mT flux

swing

C. To calculate temperature rise, use the following formula:

Temperature Rise (C) = 63 * (Core Loss(W) + Copper Loss (W))

3.

500Vrms Hi-Pot between pins 5 & 6.

4.

NL versions, which use triple insulated Teflon wire on the drive winding and magnetic

wire on the gate windings , are TUV certified. 600Vrms isolation rating is provided

between drive and gate windings.

ANL versions, which use triple insulated wire on both the drive and gate windings,

are compliant with IEC 61558, IEC 61010 & IEC 60601. 1000Vrms isolation rating is

provided between all winding except those terminate to pins 5 & 6.
