Datasheet

16-Pin SSOP 4-Channel Phototransistor Optocoupler with 3750 Vrms Isolation for Signal Isolation

The ELQ3H7(TA) is a 4-channel phototransistor optocoupler from Everlight, designed for high-density signal isolation in industrial, telecom, and power electronics. It integrates four infrared LEDs optically coupled to four phototransistor outputs within a compact 16-pin SSOP SMD package featuring a low 2.0 mm profile. This multi-channel configuration helps reduce PCB area while maintaining strong electrical isolation between control and load circuits.

With a high isolation voltage rating of 3750 Vrms and a wide CTR range of 50% to 600% at IF = 5 mA, the ELQ3H7(TA) supports reliable signal transmission across different voltage domains. The device operates over an extended temperature range and complies with major international safety standards including UL, VDE, and CQC. Supplied in tape-and-reel (TA) packaging, it is optimised for automated SMT assembly and is fully RoHS, REACH, and halogen-free compliant, making it suitable for modern, environmentally responsible designs.
