It provides 5000Vrms of galvanic isolation between a DC input LED and a transistor output with base access. The 100% to 200% current transfer ratio at 10mA forward current gives you a predictable gain window for translating logic levels across an isolation boundary. ## 70V output and 50mA drive — what it handles The output transistor is rated for 70V collector-emitter voltage and 50mA continuous current. That 70V ceiling is the key number for driving relays, solenoids, or higher-voltage logic inputs on the isolated side. The 400mV Vce saturation at rated current means minimal voltage drop when the transistor is on, so you keep most of the supply headroom for the load. ## Switching speed — 2µs edges That puts the useful switching frequency around 50-100 kHz for most applications. For higher-speed isolation (like serial interfaces), you'd step up to a digital isolator or a faster optocoupler family. The base pin access lets you tailor the switching threshold with an external resistor if needed.","metaTitle":"CNY117-3 Optocoupler, 5000Vrms Isolation, 100-200% CTR","metaDescription":"CNY117-3 optocoupler from Vishay: 5000Vrms isolation, 100-200% CTR at 10mA, 70V output, -55°C to 110°C.

The CNY117-3 guarantees 100% to 200% CTR at 10mA, while the CNY117-1 has a lower range (typically 40-80% at the same test condition).
