NSL-26 Optocouplers Features • • • • Hermetic photocell Compact, moisture resistant package Low LED current Passive resistance output Description 12.7 min. 25.4 min. Color dot Photocell 2.54 5.08 This optocoupler consists of an LED input optically coupled to a hermetic photocell. The photocell resistance is high when the LED current is “off” and low when the LED current is “on”. + ∅ 0.38-0.54 on all leads 10.4 - 10.9 Absolute Maximum Ratings Storage Temperature Operating Temperature Soldering Temperature (1) Isolation Voltage (peak) LED -40 to +75°C -40 to +75°C 260°C 2000V Notes: 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. Cathode short lead 8.2 - 9.4 Dimensions in mm.
