Description
These devices consist of a gallium arsenide infrared
emitting diode optically coupled to a monolithic silicon
phototransistor detector, in a surface mountable, small
outline, plastic package. They are ideally suited for high
density applications, and eliminate the need for through-
the-board mounting.
(add option “V” for VDE approval, i.e, MOC205VM)
Closely matched current transfer ratios
Convenient plastic SOIC-8 surface mountable
package style
Minimum BV
CEO
of 70 Volts guaranteed
Standard SOIC-8 footprint, with 0.050" lead spacing
Compatible with dual wave, vapor phase and
IR reflow soldering
High input-output isolation of 2500 V
AC(rms)
guaranteed
Applications
■
Feedback control circuits
■
Interfacing and coupling systems of different
potentials and impedances
■
General purpose switching circuits
■
Monitor and detection circuits

Absolute Maximum Ratings
(T
A
= 25°C Unless otherwise specified)
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.
