NSL-28 Datasheet, PDF (1/1 Pages) Silonex Inc. – Optocoupler

NSL-28 & NSL-28AA
Optocoupler
Features
• Compact, moisture resistant package
• Low LED current
• Passive resistance output
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”.

Note:
(1) >2 mm from case for <5 sec.
(2) Derate linearly to 0 at 75°C
(3) The Rise Time, T_R, is the time required for
the dark to light change in conductance to
reach 63% of its final value.
