Optotriac EB836632283 5kV 400V optocoupler / triac driver module

Optotriac EB836632283 is an optocoupler/triac driver module designed to provide high-voltage isolation and reliable AC switching. Specified for 5 kV isolation and capable of driving loads up to 400 V, this device separates the low-voltage control side from the high-voltage load side while delivering the gate current required to trigger TRIACs. Its compact module form factor allows integration into control boards for industrial automation, lighting control, motor starters and similar AC switching applications.

Advantages

The module provides galvanic isolation up to 5 kV between control and load circuits, reducing risk of damage and improving operator safety. It supports AC load voltages up to 400 V and is optimized to supply the drive current waveform needed to reliably trigger TRIACs. The integrated optocoupler reduces component count and simplifies PCB layout compared with discrete solutions. The module’s design focuses on predictable switching behavior and compatibility with common TRIAC-based loads.

Suitable for

• Industrial control systems and PLC interfacing
• Motor drive starters and soft-start circuits
• AC lighting control, including dimming and switching
• Household and commercial appliance control with isolated triggering
• Equipment requiring reinforced isolation between low-voltage logic and mains

Key specifications

• Insulation rating: 5 kV isolation between input and output
• Maximum load voltage: up to 400 V AC
• Function: optically isolated TRIAC driver / optocoupler
• Output type: TRIAC gate driver suitable for AC switching
• Module format: compact PCB-mountable optocoupler module

How to use

Connect the control-side LED input to the low-voltage control circuit with appropriate current-limiting resistor or driver as required by the control logic. The output side connects between the TRIAC gate and reference on the mains-load side; ensure correct polarity and compliance with the TRIAC manufacturer’s gate drive requirements. Observe recommended creepage and clearance distances on the PCB to maintain the specified 5 kV isolation. Use proper heat dissipation and follow safety practices for mains-voltage circuitry during installation and testing.

Usage recommendations

Verify gate trigger current and holding current of the target TRIAC to ensure reliable firing when driven through this optotriac module. Maintain appropriate PCB spacing and use protective components such as snubbers or RC networks if the load is inductive. Perform isolation and hipot testing after assembly to confirm insulation integrity and follow local electrical safety standards when integrating the module into mains-connected equipment.
