4. Low duty cycle pulse techniques are used during test to maintain junction temperature as close to
ambient temperature as possible.
5.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 2.0uS for it to come out of saturatiion.
³
This condition will shorten the off time at frequencies ³ 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:
