A5. Low duty cycle pulse techniques are used during test to maintain junction temperature as close to ambient temperature as possible. If the output switch is driven into hard saturation (non−Darlington configuration) at low switch currents (≤ 3. A) and high driver currents(≥ 3. A), it may take up to 2. This condition will shorten the off time at frequencies ≥ 3. Hz, and ismagnified at high temperatures.
This condition does not occur with a Darlington configuration, since the output switch cannot saturate. If anon−Darlington configuration is used, the following output drive condition is recommended: Forced b of output switch : ICIC outputdriver – 7. A*w. 10* The 1. 00 W resistor in the emitter of the driver device requires about 7. A before the output switch conducts.
