Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., X001) against the required package type, as the base model may correspond to different physical configurations. Confirm RoHS compliance status and check for end-of-life notices or production discontinuation announcements from the manufacturer before finalizing procurement plans.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when dual-channel isolation within a single package is required to save board space. Ensure the application voltage does not exceed the 70 V collector-emitter limit. Consider the thermal operating range of -55°C to +100°C for environmental compatibility. Verify that the CTR range meets the drive requirements of the receiving circuitry.

Transistor, Photovoltaic Output Optoisolators Part Context

The ILD615 series belongs to Vishay's family of multi-channel phototransistor optocouplers. These devices are designed to provide galvanic isolation between input and output circuits. The dual-channel variant allows for independent signal paths within a compact DIP-8 package, offering a solution for applications needing multiple isolated channels without increasing component count significantly.
