Additional Details:

The TLP1200 has a typical isolation voltage of several kilovolts. The current transfer ratio (CTR) is an important parameter that specifies the ratio of output current to input current. The switching speed is typically in the microseconds range. The forward voltage of the infrared LED is typically around 1.2V. The collector-emitter voltage of the phototransistor is a key specification. It is important to follow the manufacturer's recommendations for operating conditions to ensure proper performance and reliability. Safety standards such as UL and VDE may apply.
