MOC3021: 6-Pin DIP 400V Random Phase Triac Driver Output Optocoupler PRICE— 15 QUANTITY REMAINING—10 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. Features
  • 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 QUANTITY REMAINING—20 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
  • Simplifies Logic Control of 240 VAC Power
  • Zero Voltage Crossing to Minimize Conducted and Radiated Line Noise
  • 800 V Peak Blocking Voltage
FOD4118: 6-Pin DIP 800V Zero Crossing Triac Driver Output Optocoupler PRICE— 70 QUANTITY REMAINING—4 The FOD4118 device consist of an infrared emitting diode coupled to a hybrid triac formed with two inverse parallel SCRs which form the triac function capable of driving discrete triacs. The FOD4118 utilize a high efficiency infrared emitting diode which offers an improved trigger sensitivity. These devices are housed in a standard 6-pin dual in-line (DIP) package. Features
  •  300mA on-state current
  • Zero-voltage crossing
  • High blocking voltage -800V
