High Insulation Voltage -MBd Digital Optocoupler Description The ACNV26 is an optically coupled gate that combines an AlGaAs light-emitting diode and an integrated photo detector housed in a widebody package. The distance-throughinsulation (DTI) between the emitting diode and photo-detector is at 2 mm. The output of the detector IC is an open collector Schottky clamped transistor. The internal shield provides a guaranteed common mode transient immunity specification of 2 kv/μs at V cm = V. With creepage and clearance of greater than mm, ACNV26 is designed to provide high isolation voltage (7 V rms ). It can withstand a continuous high working voltage of 2262 V peak and a surge voltage of 2, V peak, meeting IEC6747--, UL, and CSA standard for reinforced insulation. ACNV26 provides the high insulation voltage protection at a high data rate of MBd. Features High voltage insulation with minimum -mm creepage and clearance 2 kv/μs minimum common mode rejection (CMR) at V CM = V High speed: MBd typical TTL compatible Open collector output Guaranteed AC and DC performance over wide temperature: 4 C to + C Available in -pin widebody packages Safety approval: Approval at 7 V rms for minute per UL77 CSA IEC/EN/DIN EN 6747-- with V iorm = 2262 V peak CAUTION It is advised that normal static precautions be taken in handling and assembly of this component to prevent damage and/or degradation which may be induced by ESD.
