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.

FEATURES

• Underwriters Laboratories (UL) recognized - 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 1500 V/µs typical, 600 V/µs guaranteed

• Compatible with Fairchild’s FKPF12N80 discrete power triac

APPLICATIONS

• Solenoid/valve controls

• Lighting controls

• Static power switches

•AC motor drives

•Temperature controls

• E.M. contactors

•AC motor starters

• Solid state relays

*Typical values at T

A

= 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.
