EL3081 equivalent to MOC3081 optocoupler

Description:

The EL3081 is a zero-voltage crossing photocoupler that provides electrical isolation and signal transmission between low-voltage control circuits and high-voltage AC power lines. It features a built-in GaAs infrared LED (emitter) optically coupled to a monolithic silicon zero-voltage crossing phototriac (detector). This design ensures the TRIAC triggers only at the zero-crossing point of the AC waveform, minimizing electromagnetic interference (EMI) and improving operational safety.

Key Features:

• Zero-voltage crossing operation minimizes EMI and improves safety
• High isolation voltage (typically 5000Vrms) for robust isolation between control and power circuits
• 600V peak breakdown voltage for handling AC power lines
• Drives TRIACs for controlling AC loads
• Compact 6-pin DIP package for space-saving integration

Technical Specifications:

• Package Type: 6-pin DIP
• Isolation Voltage: 5000 Vrms (typical)
• Peak Breakdown Voltage: 600V (typical)
• Input Current (LED): Refer to datasheet for specific value (typically in the range of 10mA)
• Output Current (TRIAC): Refer to datasheet for specific value (typically in the range of 100mA)
• Operating Temperature Range: Refer to datasheet (commercial grade typical)

Applications:

• Solid-state relays for AC load control (lights, motors, etc.)
• Industrial control systems with AC power interfaces
• Optocouplers in TRIAC driver circuits for isolated switching
• Motor speed control applications using TRIACS
• Home automation systems with AC device control (consider safety regulations)
