NOTES:
1. Maximum package power dissipation limits must be observed.
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 (< 300 mA) and
high driver
currents (>30 mA), it may take up to 2.0 µs 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 cannot
saturate If a non Darlington configuration is used, the following output drive condition is
recommended
Forced β of output switch = IC, output/(Ic, driver -7.0 mA*) > 10
*The 100 Ω. resistor in the emitter of the driver device requires about 7.0 mA before the output switch conducts
