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 1500V/µs typical, 600V/µs guaranteed

■

Compatible with Fairchild’s FKPF12N80 discrete power triac

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.

Absolute Maximum Ratings

(T

= 25°C unless otherwise noted)

A

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.
