4-Pin SSOP Phototransistor Optocoupler with 3750 Vrms Isolation for Signal and Power Control Applications
The EL3H7(B)(TA)-G is a high-reliability phototransistor optocoupler from Everlight, designed to provide strong electrical isolation between input and output circuits in compact electronic systems. It integrates an infrared emitting diode optically coupled to a phototransistor detector, housed in a compact 4-pin SSOP SMD package with a low 2.0 mm profile. This construction makes it suitable for space-constrained PCB designs requiring safe and stable signal transmission across different voltage domains.
This variant belongs to the CTR rank B, offering a current transfer ratio of 130% to 260% at IF = 5 mA, making it well suited for logic signal isolation, DC-DC converters, and industrial control circuits. With a high isolation voltage of 3750 Vrms, wide operating temperature range, and multiple international safety approvals (UL, VDE, SEMKO, NEMKO, DEMKO, FIMKO), the EL3H7(B)(TA)-G ensures dependable long-term performance. The TA tape-and-reel packaging supports automated assembly, while the halogen-free and RoHS-compliant construction meets modern environmental and regulatory requirements.
