The onsemi CNY17F2300 is a single-channel optoisolator in a 6-DIP through-hole package, with a DC input LED and a phototransistor output. It provides 5300Vrms galvanic isolation between input and output circuits, making it suitable for signal isolation in industrial control, power supply feedback, and medical equipment where high isolation voltage is required. The current transfer ratio (CTR) is specified at 63% minimum and 125% maximum, measured at a forward current of 10 mA. This binning ensures consistent gain across the operating temperature range of -55°C to 100°C, which covers industrial and some military-grade environments. Switching performance is characterized by a 1 µs rise time and 2 µs fall time typical, with turn-on and turn-off times of 2 µs and 3 µs respectively. The output transistor can handle up to 70 V and 50 mA continuous, with a Vce saturation voltage of 300 mV maximum at the rated output current.
No stock-holding claim is made; each lot is sourced per the buyer's quantity and date-code requirements.
The tube packaging is suitable for hand-insertion or wave-solder assembly in low-to-medium volume production. The base product number is CNY17, indicating this is a member of the CNY17 family. The 'F2300' suffix denotes the CTR bin and lead-form variant. Designers should verify the pinout matches the existing PCB layout — the standard DIP-6 pinout for this family is consistent across most manufacturers.
