DESCRIPTION
The MOC3081M, MOC3082M and MOC3083M devices consist of a GaAs infrared emitting diode optically coupled to a monolithic
silicon detector performing the function of a zero voltage crossing bilateral triac driver.
They are designed for use with a discrete power triac in the interface of logic systems to equipment powered from 240 VAC lines,
such as solid-state relays, industrial controls, motors, solenoids and consumer appliances, etc.

*Typical values at T

= 25°C
Note
1. Test voltage must be applied within dv/dt rating.
2. All devices are guaranteed to trigger at an I
F
value less than or equal to max I
FT
. Therefore, recommended operating I
F
lies
between max I
FT
(15 mA for MOC3081M, 10 mA for MOC3082M, 5 mA for MOC3083M) and absolute max I
F
(60 mA).
3. This is static dv/dt. See Figure 9 for test circuit. Commutating dv/dt is a function of the load-driving thyristor(s) only.
4. Isolation surge voltage, V
ISO
, is an internal device dielectric breakdown rating. For this test, Pins 1 and 2 are common,
and Pins 4, 5 and 6 are common.
