Additional Details:

The ACNY17-3 has a minimum isolation voltage of 5000 VRMS. The current transfer ratio (CTR) is typically between 50% and 600%. The forward voltage of the LED is typically 1.4V, and the forward current is typically 10mA. The collector-emitter voltage of the phototransistor is up to 70V. The operating temperature range is -55°C to +100°C. The package is a DIP-4 (Dual In-Line Package) or an SMD-4 (Surface Mount Device) package. It is commonly used in applications where electrical isolation and noise immunity are required. The optocoupler can be used to isolate digital signals, analog signals, or power signals. The high isolation voltage ensures safety in high-voltage applications. The CTR is categorized, and the '3' suffix indicates a specific CTR range.
