Each OLH 300 has a light emitting diode and an integrated photodiode transistor detector mounted and coupled in a ceramic substrate inside a hermetic TO-5 package providing 1000 Vdc electrical isolation between input and output. The integrated photo-diode transistor improves switching speed by orders of magnitude as compared to standard photo transistors, by reducing the base to collector capacitance. The internal shield provides excellent common-mode immunity performance. NOTES: 1. Measured between pins 1,2 and 3 shorted together and pins 5,6 and 7 shorted together.
