The 4N31, 4N32(1) and 4N33(1) devices consist of a gallium arsenide infrared emitting diode optically coupled to a monolithic silicon photodarlington detector. This series is designed for use in applications requiring high collector output currents at lower input currents. Higher Sensitivity to Low Input Drive Current Meets or Exceeds All JEDEC Registered Specifications To order devices that are tested and marked per VDE 0884 requirements, the suffix "V" must be included at end of part number. VDE is a test option.

1. Difference in 4N32 and 4N33 is JEDEC Registration for VISO only. All Motorola 6�Pin devices exceed JEDEC specification and are 7500 Vac(pk). The same applies for 4N29 and 4N30. 2. Isolation surge voltage is an internal device dielectric breakdown rating. For this test, Pins 1 and 2 are common, and Pins 4, 5 and 6 are common. 3. Refer to Quality and Reliability Section in Opto Data Book for information on test conditions.Preferred devices are Motorola recommended choices for future use and best overall value.

* Indicates JEDEC Registered Data. All Motorola 6�pin devices have VISO rating of 7500 Vac(pk). 1. Always design to the specified minimum/maximum electrical limits (where applicable). 2. Current Transfer Ratio (CTR) = IC/IF 100%. 3. Pulse Test: Pulse Width = 300 �s, Duty Cycle 2%. 4. For this test, Pins 1 and 2 are common and Pins 4, 5 and 6 are common. 5. Isolation Surge Voltage, VISO, is an internal device dielectric breakdown rating. 6. For test circuit setup and waveforms, refer to Figure 11.
