Specifications: The APV1125S offers a balanced performance profile with 12µA Isc and 8V Voc. It operates with a standard 0.5mA input current but has a slightly higher LED forward voltage range of 1.3-1.6VDC. Its switching times are 400µs (on) and a fast 30µs (off). Like all models in this series, it provides 2500Vrms of safety isolation and 10^10Ω isolation resistance in a compact, surface-mount SOP-4 package rated for -40°C to 85°C. Application Scenarios: This driver provides a good middle ground between current capability and speed. It is suitable for a wide range of general-purpose isolated switching applications, such as in programmable logic controller (PLC) output modules, for isolated enable/disable control in test and measurement equipment, and in low-power motor drive interfaces, where its performance offers versatility for various medium-current, medium-voltage MOSFETs.
