NSL-28 & NSL-28AA Optocoupler Features • • • Compact, moisture resistant package Low LED current Passive resistance output 12.7 min. 12.7 min. LED Photocell 2.54 + Description This optocoupler consists of an LED input optically coupled to a photocell. The photocell resistance is high when the LED current is “off” and low resistance when the LED current is “on”. ∅ 0.38-0.54 2.54 7.6 - 8.1 on all leads Color dot Note: -40 to +75°C -40 to +75°C 260°C 2000V (1) >2 mm from case for <5 sec. (2) Derate linearly to 0 at 75°C (3) The Rise Time, TR, is the time required for the dark to light change in conductance to reach 63% of its final value. Dimensions in mm.
