The top waveform shows the output of a current probe on the base (V
CURR-MON
, scaled at
1V/A) swinging from +2.5A to -2.5A, approximately.
The bottom waveform shows the collector voltage starting to rise to 10% of its final
value after a delay of 960 ns. This is t
S
, the storage time. MIL-PRF-19500/464G
specifies t
S
to be 2.0 us or less, so this particular device meets the test requirements.
The photo below is the same, except that the cursors measure the collector 10%-90%
rise time, corresponding to the turn-off time (t
OFF
):
t
OFF
is measured as 800 ns. MIL-PRF-19500/464G specifies t
OFF
to be 3.0 us or less, so
this particular device meets the test requirements.
An On Semi 2N5686G (datecode BM1129) transistor was used for this test.
The waveform below shows the VMON and VIN waveforms that correspond to the last
two photos:
