The onsemi 6N138WV is a single-channel optoisolator in an 8-DIP through-hole package, with a Darlington output transistor that includes a base-access pin for external bias or speed-up networks. Rated for 2500Vrms isolation between input and output, it suits galvanic isolation in industrial signal interfaces, PLC digital inputs, and motor-drive feedback paths where the 300% minimum current transfer ratio at 1.6mA forward current ensures reliable logic-level translation across the isolation barrier. The Darlington output delivers up to 60mA per channel, with a typical turn-on time of 1.5µs and turn-off of 7µs — fast enough for 100 kHz data rates in most control applications.
For existing BOM lines, the part is sourced through independent distribution channels against an RFQ.
