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 pro-

vides 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)
