Note) 2. Low duty cycle pulse techniques are used during test to maintain junction temperature as close to ambient temperature as possible.
3. 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 2.0μS 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 ;
Forced βof output switch :

≥ 10
IC driver-7.0mA *
* The 100Ω resistor in the emitter of the driver device requires about 7.0mA before the output switch conducts.
