Transistor, Photovoltaic Output Optoisolators datasheet and documents for ILD256T

ILD256T

Transistor, Photovoltaic Output Optoisolators Overview

The ILD256T is a dual-channel optocoupler manufactured by Vishay Semiconductor Opto Division. Each channel integrates two infrared emitters coupled to a silicon NPN phototransistor detector, designed for AC input applications. The device provides electrical isolation with a voltage rating of 4000Vrms and supports a minimum current transfer ratio of 20% at an input current of 10mA. It is housed in an 8-SOIC package with a width of 3.90mm. The component is currently classified as obsolete and no longer manufactured.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

This component is officially marked as obsolete and is no longer manufactured by Vishay Semiconductor Opto Division. Procurement should focus on identifying verified replacement parts or alternative components that meet the same technical specifications. Verify availability through authorized distributors who may hold remaining stock or offer equivalent substitutes. Ensure any replacement maintains the required isolation voltage and channel configuration.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component only if legacy compatibility is required, as it is discontinued. Designers should evaluate modern alternatives that offer similar dual-channel performance and isolation ratings. Consider the 8-SOIC footprint when planning board layouts for potential replacements. Verify that substitute devices support AC input and provide comparable current transfer ratios to ensure circuit functionality remains intact during migration.

Transistor, Photovoltaic Output Optoisolators Part Context

The ILD256T belongs to Vishay's family of transistor output optocouplers. It shares architectural similarities with other dual-channel variants but is distinguished by its specific emitter configuration and SOIC packaging. This part was designed for applications needing compact, high-isolation solutions. Its obsolescence reflects typical lifecycle management in semiconductor manufacturing, prompting users to transition to newer generations of optoisolators.
