Each OLI 400 has a light emitting diode and an integrated photodiode-darlington detector IC mounted and coupled in a miniature custom ceramic package providing 1500 Vdc electrical isolation between input and output. The darlington detector has an integrated base - emitter resistor for superior high temperature performance. The split darlington design permits lower output saturation voltage and higher switching speed operation than possible with conventional photodarlington design. Device mounting is achieved by standard hybrid assembly with non-conductive epoxies. Gold or aluminum wire bonding can be used to make electrical connections for maximum placement flexibility 3. Notes: 1. Measured between pins 1 and 6 shorted together and pins 2, 3, 4, and 5 shorted together. TA =25°C and duration = 1 second. 2. Current transfer ratio is defined as the ratio of output collector current, Ic to the forward LED current, IF, times 100%. 3.
