NTE3045
Optoisolator
Silicon NPN Darlington Phototransistor Output
Description:
The NTE3045 is a gallium arsenide LED optically coupled to a Silicon Photo Darlington transistor in
a 6–Lead DIP type package designed for applications requiring electrical isolation, high breakdown
voltage, and high current transfer ratios. Characterized for use as telephone relay drivers but provides excellent performance in interfacing and coupling systems, phase and feedback controls, solid
state relays, and general purpose switching circuits.
Features:
D High Sensitivity to Low Input Drive Current
D High Collector–Emitter Breakdown Voltage: V(BR)CEO = 80V (Min)
D High Input–Output Isolation Guaranteed: VISO = 7500V (Peak)
Absolute Maximum Ratings: (TA = +25°C, unless otherwise specified)
