A1458 Optocoupler Datasheet _top_ [2027]

To get the most out of your A1458, keep these design principles in mind:

This is the ratio of output current to input current. For the A1458, this is generally between 50% and 600%, categorized into different "ranks" (e.g., Rank L, Rank A). Pinout Configuration a1458 optocoupler datasheet

): Typically 2,500 to 5,000 Vrms. This is the "survival" rating for the gap between input and output. To get the most out of your A1458,

Optocouplers have a "Rise Time" and "Fall Time." If you are sending high-speed PWM signals (above 10kHz), check the datasheet for the switching speed to ensure the signal doesn't become distorted. This is the "survival" rating for the gap

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