Typical Characteristics
Note A:
All Characteristic data in the above graphs has been developed from actual products tested at 25°C. This data is considered typical data for the ISR.
Note B:
SOA curves represent operating conditions at which the internal components are at or below the manufacturer’s maximum rated operating temperatures.
