4170Vrms isolation and CTR range for BOM fit
Rated for 4170Vrms isolation, this optoisolator provides reinforced insulation for safety-barrier applications in industrial power supplies, motor drives, and PLC digital input modules. The 160% to 320% current transfer ratio at 10 mA forward current gives the designer a predictable gain window — the minimum CTR of 160% ensures the output transistor saturates reliably into a known load, while the 320% ceiling prevents unexpected saturation in high-gain loops. Switching speed is specified with a 2 µs turn-on and 3 µs turn-off typical, and rise/fall times of 4 µs / 3.5 µs max. This suits 10-100 kHz isolated data paths or slow digital I/O where the propagation delay is well within the PLC scan cycle.
Housed in a 6-SMD Gull Wing package with a 6-SMD supplier device package designation. Supplied in Tape & Reel for automated pick-and-place. The 70V output maximum and 50 mA continuous output current handle 24V PLC logic rails and low-power relay drivers.
