Low duty cycle pulse techniques are used during test to maintain junction temperature as close to ambient as possible. 6 Note 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 ms 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 cannot saturate. If a non-Darlington configuration is used, the following output drive condition is recommended: Forced of output switch: lC output lC driver - 7.0 mA * 10 * The 100 resistor in the emitter of the driver device requires about 7.0 mA before the output switch conducts.
