TIME (ms)
Notes:
1. All voltages are measured with automated test set using 35
msec test time. Longer or shorter test times will have a
corresponding effect on the measured value due to the heat-
ing effects.
2. Current Pulse rises to peak value of I
PP
in 10
µ
sec and
decay to half value, I
PP
/2, in 1msec.
3. Pulse width (t
P
) is defined as the time from peak pulse
current I
PP
to the point where peak pulse current decayed
to 50% of rated I
PP
. (10
