Dark current doubles approximately every 10°C. At high temperatures, it can become significant, so ensure your pull-up resistor and logic threshold account for this. it can become significant

: Unlike standard phototransistors, the A1458 uses an integrated photodetector and output transistor with separate connections for the photodiode bias and collector. This design reduces base-collector capacitance, allowing for speeds up to 100 times faster than conventional couplers.
