ILD2

Transistor, Photovoltaic Output Optoisolators Overview

The ILD2-X009T is a dual-channel transistor-output optocoupler manufactured by Vishay Semiconductor Opto Division, distributed by Isocom Components. It features an isolation voltage of 5300Vrms and operates within a temperature range of -40°C to 100°C. The device utilizes an 8-SMD gull-wing package. Key electrical parameters include a maximum collector-emitter voltage of 70V, a DC forward current limit of 60mA, and a typical forward voltage of 1.25V. Output characteristics specify a 50mA channel current with a saturation voltage of 400mV. Current transfer ratios range from 100% to 500% at 10mA input. Switching times are defined by turn-on/turn-off values of 1.2µs and 2.3µs, respectively, with rise/fall times of 2.6µs and 2.2µs. This component is currently obsolete.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify component obsolescence status prior to procurement as the ILD2 series is discontinued. Confirm availability through authorized distributors or surplus suppliers like Isocom Components. Ensure compatibility with existing PCB footprints and thermal management requirements. Validate that alternative sources provide genuine Vishay products to maintain reliability standards in critical applications.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component only if dual-channel isolation within an 8-SMD package is required. Consider the specific switching speed requirements against the documented 1.2µs turn-on time. Evaluate the 5300Vrms isolation rating against system safety standards. Since the part is obsolete, assess long-term supply chain risks and potential need for redesign using modern equivalents.
