Triac Optotriac EB1430261587 5.3 kV gate, 600 V blocking voltage, OEM component

Optotriac EB1430261587 is a triac-style optocoupler designed for controlled AC switching and isolation in power electronics. The device integrates an infrared-controlled gate input with a high-voltage output stage capable of blocking up to 600 V, intended for OEM use in power control modules, solid-state relays and protective switching circuits where precise gate triggering and galvanic isolation are required.

Advantages

The component provides electrical isolation between control circuitry and AC power lines while enabling reliable gate triggering and bidirectional conduction when activated. Its specified gate characteristic supports consistent activation thresholds, and the 600 V blocking capability allows use in moderate-voltage mains and industrial power applications. As an OEM part it is suitable for direct replacement in compatible modules or for integration during device manufacturing.

Suitable for

• AC power switching in control modules and solid-state relays
• Replacement or repair of compatible electronic power modules
• Integration into designs requiring galvanic isolation between control and mains
• Protective switching and load control in industrial and appliance circuits

Key specifications

• Gate characteristic: specified for a 5.3 kV-equivalent gate response (input-to-output triggering parameter)
• Maximum blocking voltage: 600 V
• Function: bidirectional AC switching when triggered (triac/optotriac operation)
• Application class: OEM component for power control, switching and isolation

How to use

Install the optotriac in the circuit according to the manufacturer’s recommended orientation and soldering procedures for OEM components. Ensure proper input drive to the gate side using the appropriate LED current and limiting resistor so the device reaches its activation threshold. Place the component on a PCB with adequate isolation distances from mains traces and provide thermal management appropriate for the expected load and switching frequency. Verify circuit connections and perform functional testing at low voltage before applying full operating mains voltage.

Usage recommendations

Use the component only within its rated blocking voltage and ensure the control-side driver provides stable current to meet the gate specification. For repairs, confirm pinout and mechanical compatibility with the original module. Maintain safe handling practices for mains-connected circuits and follow applicable regulatory and safety standards during installation and testing.
