Procurement Notes

Verify the specific manufacturer designation and revision level against official Isocom Components documentation before integration. Confirm that the 4-DIP package dimensions and pinout match the target PCB footprint requirements. Ensure that the thermal management design accommodates the specified 200mW power dissipation under worst-case operating conditions. Validate compliance with relevant safety standards such as UL certification if required by the end application.

Selection Notes

Select this component when a single-channel transistor-output optoisolator with AC input capability is required. Consider the 5300Vrms isolation rating for applications demanding robust galvanic separation. Evaluate the 100μs switching speeds against system timing constraints. Verify that the 50mA forward current limit aligns with the driving circuit's output capabilities and that the operating temperature range suits the environmental conditions.
