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.
file #E90700, Volume 2
VDE recognized – file #102497 – add option V
(e.g., MOC3083VM)
Simplifies logic control of 240 VAC power
Zero voltage crossing
dv/dt of 1500V/µs typical, 600V/µs guaranteed
Compatible with Fairchild’s FKPF12N80 discrete
power triac

Absolute Maximum Ratings
(T
A
= 25°C unless otherwise noted)
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.

Notes:
2. Test voltage must be applied within dv/dt rating.
3. 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
(15mA for MOC3081M, 10mA for MOC3082M, 5mA for MOC3083M) and
absolute max I
F
(60mA).
4. This is static dv/dt. See Figure 9 for test circuit. Commutating dv/dt is a function of the load-driving thyristor(s) only.
5. 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.
