6-Pin DIP Zero-Cross Optoisolators Triac Driver Output
(250/400 Volt Peak)
Features
■
Simplifies logic control of 115 VAC power
■
Zero voltage crossing
■
dv/dt of 2000 V/µs typical, 1000 V/µs guaranteed
■
VDE recognized (File # 94766), ordering option V
(e.g., MOC3043VM)
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.
