Overview
The EL3H7(C)(TA)-G series from Everlight Electronics Co Ltd is a range of 4-pin Small Outline Package (SSOP) phototransistor photocouplers. These devices consist of an infrared emitting diode optically coupled to a phototransistor detector, encapsulated in a green compound. This design ensures high isolation between the input and output circuits, making them suitable for various applications requiring signal transmission between circuits of different potentials and impedances.
