ELM3023(TB)

Triac, SCR Output Optoisolators Overview

The ELM3023(TB) is a Triac and SCR output optocoupler manufactured by Everlight Electronics Co Ltd. It features a random-phase Triac driver output suitable for AC load control applications. The device utilizes surface mount technology (SMD/SMT) packaging, specifically identified as 4-SOP in some documentation, while other sources cite 6-SMD configurations for related variants. Key electrical parameters include a 3750Vrms isolation voltage and a peak repetitive off-state voltage of 400V. The component operates within a temperature range of -55°C to 100°C. It is designed for precise control signals with sensitive output characteristics.
