Datasheet for Everlight ELM304X, ELM306X, and ELM308X 4‑pin SOP zero‑cross triac photocouplers, covering features, ratings, and specifications.
The Everlight ELM304X, ELM306X and ELM308X series are 4‑pin SOP zero‑cross triac photocouplers designed for interfacing logic systems with AC power lines (110‑240 VAC). They are used in solenoid/valve controls, light controls, solid‑state relays, AC motor drivers, and other industrial or consumer applications.
The datasheet provides detailed electrical ratings such as peak breakdown voltage (400‑800 V depending on model), isolation voltage of 3750 Vrms, on‑state RMS current of 70 mA, and power dissipation up to 300 mW. Ordering information, package dimensions, soldering guidelines, and safety approvals (UL, VDE, SEMKO, NEMKO, DEMKO, FIMKO) are also included.
