Vishay’s VO617A and VO618A optocouplers: VO series packs phototransistor output in DIP packages
The DIP-4-packaged VO617A and VO618A optocouplers with a phototransistor output feature an isolation voltage of 5000V rms for switch-mode-power-supply applications. The devices achieve a 40 to 320% current-transfer ratio and an input drive current of 5 and 1 mA for the VO617A and VO618A, respectively. A creepage distance of 8 mm or more is available as an option. The SOP-4L-packaged VOL617A and VOL618A have an 8-mm or greater creepage distance and an isolation voltage of 5000V rms. Current-transfer ratio is 40 to 320% at an input drive current of 5 and 1 mA, respectively. The SSOP-4-packaged VOS618A an d VOS628A have an isolation voltage of 3750V rms and a current-transfer ratio of 63 to 320% at an input drive current of 1 mA. The VO617A and VO618A sell for $0.072 (10,000); the VOS618A and VOS628A sell for 18 and 20 cents, respectively; and the VOL617A and VOL618A sell for 28 cents.
