Input-Output Momentary VISO 3750 — — Vrms RH < 50%, t = 1 minute, a, b Withstand Voltage TA = 25°C Resistance (Input-Output) RI-O — >109 — Ω VI-O = 500 VDC c Capacitance (Input-Output) CI-O — 1.2 — p F ƒ = 1 MHz c a. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage ≥ 4500 Vrms for 1 second (leakage detection current limit, II-O ≤ 5 µA). This test is performed before the 100% production test for partial discharge (method b) shown in IEC/EN/DIN EN 60747-5-5 Insulation Characteristics Table. b. The Input-Output Momentary Withstand Voltage is a dielectric voltage rating that should not be interpreted as an input-output continuous voltage rating. For the continuous voltage rating, refer to the IEC/EN/DIN EN 60747-5-5 Insulation Characteristics Table and your equipment level safety specification. c. This is a two-terminal measurement: pins 1–4 are shorted together and pins 5–8 are shorted together.
