5300 Vrms isolation — reinforced insulation for industrial and power applications
The VO4661-X006 is a dual-channel optocoupler from Vishay that provides 5300 Vrms isolation between input and output, making it suitable for applications requiring reinforced insulation such as motor drives, industrial power supplies, and medical equipment. The open-drain output and 10 MBd data rate allow it to interface directly with logic-level circuits like microcontrollers, FPGAs, or PLC I/O modules without additional level translation.
10 MBd data rate and 15 kV/µs CMTI — fast switching in noisy environments
With a typical rise/fall time of 23 ns and 7 ns respectively, and a propagation delay of 75 ns max, the VO4661-X006 handles 10 MBd signaling cleanly — fast enough for industrial fieldbus interfaces like RS-485, CAN, or PWM-driven gate drivers. The 15 kV/µs common-mode transient immunity (CMTI) ensures the output stays valid when large voltage spikes couple across the isolation barrier, a common issue in inverter and motor-drive stages where IGBTs switch at high dV/dt.
Through-hole 8-DIP — easy to inspect and rework
Housed in an 8-DIP package with 0.400-inch (10.16 mm) body width, the VO4661-X006 is a through-hole device. This package is straightforward to hand-solder, inspect, and rework — a practical choice for prototype builds, low-volume production, or maintenance spares where board rework is expected.
