6-PIN DIP ZERO-CROSS
OPTOISOLATORS TRIAC DRIVER OUTPUT
(250/400 VOLT PEAK)
MOC3031M
DESCRIPTION
The MOC303XM and MOC304XM devices consist of a AlGaAs
infrared emitting diode optically coupled to a monolithic silicon
detector performing the function of a zero voltage crossing bilat-
eral triac driver.
They are designed for use with a triac in the interface of logic
systems to equipment powered from 115 VAC lines, such as
teletypewriters, CRTs, solid-state relays, industrial controls,
printers, motors, solenoids and consumer appliances, etc.

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 MOC3031M & MOC3041M, 10 mA for MOC3032M & MOC3042M, 5 mA for MOC3033M & MOC3043M) 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.
