Safe Operating Area

Ambient temperature Ta (°C)

Curves should be applied in thermal limited area. The figure

shows thermal resistance per device versus pulse width.

These curves are obtained by using single nonrepetitive

pulse under the condition of devices attached on a circuit

board with no heat sink.
