Micropac Industries, Inc. Mii Optocoupler 66171-300

The Mii 66171 is an optically coupled isolator, consisting of four GaAlAs LEDs and four silicon phototransistors mounted and coupled in a miniature surface mount hermetic leadless chip carrier. The 66171 uses an LED proven to be more tolerant to proton radiation. All electrical characteristics of each channel are similar to the JEDEC registered 4N49. Each unit contains four channels. These solid state couplers are ideal for designs where board space, device weight and radiation tolerance are important design considerations. Features: • High Reliability • Base lead provided for conventional transistor biasing • Very high gain, high voltage transistor • Stability over wide temperature range. • +1kVdc electrical isolation • Screening available
