Characteristics

The next curve on the next page shows the behavior with RS = 15 k

Ω and C = 1 µF.

Ω, C = 1 µF and VBO = 225 V

Peak current limit

This component is designed to withstand ITRM = 190 A for a pulse duration of 10 µs for an

ambient temperature of 120° C in repetitive surge. The curve of peak current versus the

pulse duration allows us to verify if the application is within the FLC operating limit.

Power losses (for 10 µs, see Figure 3)

To evaluate the power losses, please use the following equations:

–

For the thyristor: P = 1.18 x IT(AV) + 0.035 I

T(RMS)

–

For the diode: P = 0.67 x IF(AV) + 0.106 I
