ILD250

Transistor, Photovoltaic Output Optoisolators Overview

The ILD250 is a dual-channel optocoupler manufactured by Vishay Semiconductor Opto Division. It features two isolated channels within a single industry-standard DIP package, designed for applications requiring bidirectional input and polarity-insensitive operation. The device incorporates built-in reverse polarity protection and offers improved current transfer ratio symmetry. Key electrical specifications include a maximum isolation voltage of 5300 Vrms, a DC forward current of 60 mA, and a collector-emitter saturation voltage of 400 mV. The component supports an operating temperature range from -55°C to 100°C.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix code (e.g., X009) against the manufacturer's datasheet to ensure correct binning and performance characteristics. Confirm RoHS compliance status as historical batches may vary. Check for obsolescence notices or lifecycle changes directly with Vishay before finalizing procurement plans.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when dual-channel isolation is required within a compact footprint. Ensure the application voltage does not exceed the 5300 Vrms isolation rating. Verify that the 60 mA forward current limit meets the drive requirements of the connected LED circuit. Consider thermal management if operating near the upper temperature limit.

Transistor, Photovoltaic Output Optoisolators Part Context

The ILD250 belongs to the IL25x series of optocouplers, which includes single-channel variants like the IL251. This series is characterized by high isolation voltages and robust input protection features. It serves as a specialized solution for applications needing multiple isolated signals without increasing board space significantly compared to using separate single-channel devices.
