3C91C Description

Short technical summary and product information.

The 3C91C from TT Electronics/BI is a high-reliability optoisolator designed for applications requiring robust electrical isolation. It provides 1kVDC isolation between input and output, making it suitable for use in industrial equipment, medical devices, and office environments, especially where electrical noise or 'dirty' environments are a concern.

 

This optoisolator utilizes a phototransistor sensor type and is housed in a TO-72 hermetically sealed package. It offers a minimum current transfer ratio (CTR) of 30% at 10mA and a maximum CTR of 200% at 10mA. The device operates within a temperature range of -55°C to 125°C and has a maximum output current of 50 mA. The input type is DC, and it features a wavelength of 935nm.

 

Designed for through-hole mounting, the 3C91C has a lead length of 0.5 inches. Its specifications include a VCE saturation of 400mV maximum and rise/fall times of 9µs and 6µs respectively. The part is listed as RoHS3 Compliant and has an MSL rating of 1 Unlimited.
