No successor part number is recorded in the manufacturer's documentation. Quantities are lot-specific and confirmed at RFQ — no stock-holding claim is made here. ## Isolation and switching performance Rated for 5300 Vrms isolation — sufficient for reinforced insulation in mains-isolated circuits where the primary-to-secondary withstand must exceed 4 kV. Minimum current transfer ratio of 10 % at 10 mA forward current means the output transistor saturates with a modest LED drive; the 500 mV Vce saturation ceiling keeps the logic-level drop within TTL/CMOS thresholds. Typical turn-on and turn-off times of 2 µs each — adequate for 100 kHz switching in feedback loops or isolated gate drive, but not for high-speed data links. Supplied in a 6-SMD gull wing package (6-SMD supplier device package). The gull-wing leads suit reflow soldering and allow visual inspection of the solder joint. Surface-mount footprint with a 1.27 mm pitch — compatible with standard SOIC-6 land patterns. The tube packaging is a single-tube quantity; no tape-and-reel option is listed.","metaTitle":"onsemi 4N283S Optoisolator, 5300 Vrms, Transistor Output","metaDescription":"onsemi 4N283S single-channel optoisolator, 5300 Vrms isolation, transistor output with base, 6-SMD gull wing.
