MOC3021: 6-Pin DIP 400V Random Phase Triac Driver Output Optocoupler

PRICE--- 15
The MOC301XM and MOC302XM series are optically isolated triac driver devices. These devices contain a GaAs infrared emitting diode and a light activated silicon bilateral switch, which functions like a triac. They are designed for interfacing between electronic controls and power triacs to control resistive and inductive loads for 115 VAC operations.
  • Excellent IFT Stability - IR Emitting Diode Has Low Degradation• 
  • Peak Blocking Voltage -400 V

MOC3083: 6-Pin DIP 800V Zero Crossing Triac Driver Output Optocoupler
PRICE--- 25

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.
  • Simplifies Logic Control of 240 VAC Power
