Note4: Low Duty cycle pulse techniques are used during test to maintain junction temp. as close to ambient temp. as possible.
Note5: If the output switch is driven into hard saturation (non-Darlington configuration) at low switch current (≤300mA) and high driver currents
(≥30mA). It may take up to 2.0 µs for it to come out of saturation. This condition will shorten the off time at frequencies ≥ 30 kHz. And is
magnified at high temperatures. This condition does not occur with a Darlington configuration. Since the output switch can not saturate. If a non-
Darlington configuration is used the following output drive condition is recommended:
The 100Ω resistor is the emitter of the driver device requires about 7.0 mA before the output switch conducts
