NTE3093 Optoisolator NPN Split Darlington Output
Description: The NTE3093 coupler uses a light emitting diode (LED) and an integrated high gain photon detector to provide 3000V DC electrical insulation, 500V/s common mode transient immunity and extremely high current transfer ratio between inut and output. Separate pins for the photodiode and output stage result in TTL compatible saturation voltages and high speed operation. Where desired, the VCC and VO terminals may be tied together to achieve conventional photodarlington operation. A base access terminal allows a gain bandwidth adjustment to be made.

The small junction sizes inherent to the design of this bipolar component increases the component's susceptibility to damage from electrostatic discharge (ESD). It is advised that normal static precautions be taken in handling and assembly of this component to prevent damage and/or degredation which may be induced by ESD.

Note 3. DC Current Transfer Ratio is defined as the ratio of output collector current (IO) to the forward LED input current (IF) times 100%. Note 6. Use of a resistor between Pin5 and Pin7 will decrease gain abd delay time. Note 7. Common mode transient immunity in Logic High level is the maximum tolerable (positive) dv cm/dt on the leading edge of the common mode pulse (VCM) to assure that the output will remain in a Logic High state (i.e. VO 2.0V). Common mode transient immunity in Logic Low level is the maximum tolerable (negative) dc cm/dt on the trailing edge of the common mode pulse signal (VCM) to assure that the output will remain in a Logic Low state (i.e. VO 0.8V). Note 8. In applications where dV/dt may exceed 50,000V/s (such as static discharge) a series resistor (RCC) should be included to protect the detector IC from destructively high surge currents. The recommended value is: 1V RCC = k 0.15 IF (mA)
