Optocoupler Datasheet - A1458

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

Over years of continuous use, the internal LED will slightly dim, effectively lowering the CTR. Design your circuit with a bit of "headroom" (using a higher current than the bare minimum) to account for aging. Conclusion

): Often rated up to 35V or 70V depending on the specific variant. Usually ranges between 50mA and 100mA. Saturation Voltage ( a1458 optocoupler datasheet

Protecting telephone lines and modem interfaces from lightning strikes or power surges. Design Tips: Working with the A1458

Why choose the A1458 over a standard transistor? Here are the most common use cases: ): Typically 2,500 to 5,000 Vrms

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.

Allowing a 3.3V or 5V MCU to trigger a 24V industrial relay or motor driver without risking a "blowback" of current. Design your circuit with a bit of "headroom"

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