Miniature Wide Bandwidth Optocoupler for Hybrid Assembly

The OLI303 is suitable for wide bandwidth analog applications. Each OLI303 has an LED and an integrated photodiode transistor detector mounted and coupled in a miniature custom ceramic package that provides 1500 VDC of electrical isolation between the input and output. The integrated photodiode transistor improves the bandwidth by orders of magnitude as compared to standard phototransistors. The internal shield provides excellent common mode immunity performance.

Device mounting is achieved by a standard hybrid assembly with non-conductive epoxies. Gold or aluminum wire bonding can be used to make electrical connections for maximum placement flexibility.
