Low duty-cycle pulse testing is used to maintain junction temperature as close to ambient temperature as possible.
In the non-Darlington configuration, if the output switch is driven into hard saturation at low switch currents (≤300 mA) and high driver
currents (≥30 mA), it may take up to 2
μs
for the switch to come out of saturation. This condition effectively shortens the off time at
frequencies
≥30
kHz, becoming magnified as temperature increases. The following output drive condition is recommended in the
non-Darlington configuration:
Forced

/ (I

≥
10, where
~7
mA is required by the 100-Ω resistor in the emitter of the driver to
forward bias the V

of the switch.
