A1458 — Optocoupler Datasheet

Used in the feedback loop to regulate output voltage while keeping the high-voltage AC side isolated from the DC output.

): Typically 2,500 to 5,000 Vrms. This is the "survival" rating for the gap between input and output. a1458 optocoupler datasheet

The A1458 is an optoisolator that uses light to transfer electrical signals between two isolated circuits. It consists of a Gallium Arsenide (GaAs) infrared LED on the input side and a high-gain phototransistor or integrated detector on the output side. Used in the feedback loop to regulate output
