Designer’s Data for “Worst Case” Conditions — The Designer’s Data Sheet permits the design of most circuits entirely from the information presented. SOA Limit
curves — representing boundaries on device characteristics — are given to facilitate “worst case” design.
Preferred devices are Motorola recommended choices for future use and best overall value.

Both leads to heat sink, with lengths as shown. Variations in RqJL(t)
below 2.0 seconds are independent of lead connections of 1/8 inch
or greater, and vary only about ±20% from the values shown. Values
for times greater than 2.0 seconds may be obtained by drawing a
curve, with the end point (at 70 seconds) taken from Figure 8, or
calculated from the notes, using the given curves as a guide. Either
typical or maximum values may be used. For RqJL(t) values at pulse
widths less than 0.1 second, the above curve can be extrapolated
down to 10 µs at a continuing slope.
