Datasheet

4-Pin SSOP Phototransistor Optocoupler with CTR Rank D and 3750 Vrms Isolation for Compact Signal Isolation

The EL3H7(D)(TA)-G is a high-gain phototransistor optocoupler from Everlight’s EL3H7-G series, designed for dependable signal isolation in compact, high-density PCB layouts. It integrates an infrared LED optically coupled to a phototransistor detector, housed in a 4-pin SSOP surface-mount package with a slim 2.0 mm profile. This structure ensures safe and noise-immune signal transmission between circuits operating at different voltage potentials.

This CTR Rank D variant delivers a current transfer ratio of 300 % to 600 % at IF = 5 mA, making it suitable for applications requiring higher gain margins. With a 3750 Vrms isolation rating, wide operating temperature range, and multiple global safety approvals including UL and VDE, the EL3H7(D)(TA)-G is well suited for DC-DC converters, programmable controllers, telecom equipment, and industrial control systems. The TA tape-and-reel packaging supports automated SMT assembly, while the halogen-free, RoHS- and REACH-compliant construction aligns with modern environmental standards.
