3.Low duty cycle pulse techniques are used during test to maintain junction temperature as close to ambient
temperature as possible.
4.If the output switch is driven into hard saturation (non-Darlington configuration) at low switch currents (
≤
300mA) and high driver
currents (
≥
30mA), it may take up to 2.0
μ
s for it to come out of saturation. This condition will shorten the off time at frequencies
≥
30kHz,
and is magnified at high temperatures. This condition does not occur with a Darlington configuration, since the output switch cannot
saturate. If a non-Darlington configuration is used, the following output drive condition is recommended :

* The 100
