1. Draw a line from Case Temperature axis to the PCB Temperature axis.
2. Draw a vertical line from the T
3. Draw a horizontal line from the intersection of the vertical line with the SOA curve to
4. Draw a new vertical line from the T
5. Draw a horizontal line from the intersection of the new vertical line with the SOA curve
TX axis intercept adjustment ≈ -0.5 ºC + 5.5 ºC - 0.8 ºC + 0.6 ºC - 1.9 ºC ≈ 2.9 ºC
Assuming T
The following example shows how the SOA current is adjusted for T
the Y-axis (Output Current). The point at which the horizontal line meets the Y-axis is
the SOA continuous current.
temperature from the original T
to the Y-axis (Output Current). The point at which the horizontal line meets the Y-axis
is the new SOA continuous current.
