The 3C91C from Telefunken is a high-reliability optoisolator designed for demanding applications requiring robust electrical isolation. Encased in a TO-72 hermetically sealed package, this component provides 1kVDC isolation between input and output, making it suitable for use in environments with high voltages or electrical noise.
Key electrical characteristics include a high current transfer ratio (CTR) with a minimum of 30% at 10mA and a maximum CTR of 2. It operates over a wide temperature range from -55°C to 125°C and utilizes a phototransistor sensor type with an emission wavelength of 935nm. The device supports a maximum collector-emitter voltage of 50V and a typical forward current of 40mA.
Applications for the 3C91C include high-voltage isolation in industrial equipment, as well as providing electrical isolation in dirty environments. Its hermetically sealed package and wide operating temperature range ensure reliability in harsh conditions. The component features through-hole mounting and a lead length of 0.5 inches.
