MB105/4C Optocoupler IC Dip 6 Pin

Description

MB105/4C Optocoupler IC Dip 6 Pin The MB105/4C is a 6-pin DIP optocoupler (optically coupled isolator) designed for electrical isolation between input and output circuits. It consists of an infrared emitter diode (IRED) on the input side and a planar NPN silicon phototransistor on the output side. This variant (/4C) features a collector-emitter breakdown voltage of 70V and belongs to current transfer ratio (CTR) group C, offering a CTR range of 100% to 200%. Features Infrared LED input coupled with NPN silicon phototransistor output for reliable optical isolation. High peak insulation voltage of 5.3kV RMS (50-60Hz sine wave) for robust electrical separation. Collector-emitter voltage rating of 70V, suitable for medium-voltage applications. Current transfer ratio (CTR) group C: 100% to 200% at IF = 10mA, VCE = 5V. Includes base connection on the phototransistor for enhanced control and flexibility. Wide operating temperature range from -55°C to +85°C. Specifications Parameter Min. Max.
