Safe Operating Area (SOA)
The safe operating area plot
provides a comprehensive summary
of the power handling limitations of a
power amplifier, including maximum
current, voltage and power as well as
the secondary breakdown region. It
shows the allowable output current
as a function of the power supply to
output voltage differential (voltage
across the conducting power device).
