ELT3063

Triac, SCR Output Optoisolators Overview

The ELT3063 is a zero-crossing Triac driver photocoupler manufactured by Everlight Electronics. It integrates an AlGaAs infrared LED emitter with a silicon photo-Triac detector in a compact 4-pin DIP package. The device provides electrical isolation of 5000 Vrms between input and output circuits. Key electrical parameters include a maximum forward current of 60 mA, a peak repetitive off-state voltage rating of 400 V, and a holding current of 280 µA. It operates within a temperature range of -55°C to +100°C.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific package variant, as the ELT3063 designation typically refers to the through-hole DIP configuration. Confirm that the required isolation voltage and off-state voltage ratings align with the target circuit design. Ensure compatibility with the intended operating temperature range before finalizing component selection.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing switching is required to reduce noise in AC load control applications. The 400 V rating suits low-voltage AC systems. Verify that the driving circuit can supply sufficient current to trigger the internal Triac reliably under all expected load conditions.

Triac, SCR Output Optoisolators Part Context

This device belongs to the family of Triac and SCR output optocouplers designed for AC power switching. It serves as an interface between low-voltage logic controllers and high-voltage AC loads. The zero-crossing feature distinguishes it from random-phase variants used for phase-angle control.

Triac, SCR Output Optoisolators Replacement Considerations

Compatible substitutes include the EL3063 series for through-hole implementations and the ELT3043 for similar isolation and voltage ratings. Verify pinout compatibility and thermal characteristics when transitioning between these models.
