IL358

Transistor, Photovoltaic Output Optoisolators Overview

The IL358 is a single-channel linear optoisolator manufactured by Vishay Semiconductor Opto Division. It features an infrared LED emitter optically coupled to two photodiodes, providing a linearized photovoltaic output. The device offers high linearity suitable for optical Digital Access Adapter (DAA) applications in telecommunications. It provides a voltage isolation rating of 3000Vrms and operates with a typical forward voltage of 1.8V and a maximum DC forward current of 30 mA. The component is housed in an 8-SOP surface-mount package.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., T) against the required tape-and-reel or tube packaging configuration. Confirm RoHS compliance status as some listings indicate lead-free versions. Check part status carefully, as this model may be marked obsolete in certain distributor catalogs; ensure availability matches project requirements before finalizing procurement.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high linearity is critical for analog signal integrity across an isolation barrier. The dual photodiode architecture enables precise linear response compared to standard digital optocouplers. Ensure the application requires photovoltaic output rather than transistor-based output. Verify that the 3000Vrms isolation rating meets the safety standards of the target system.

Transistor, Photovoltaic Output Optoisolators Part Context

The IL358 belongs to the IL35x family of linear optocouplers from Vishay. This family typically includes variants like the IL350, sharing similar internal structures of an IR LED facing multiple photodiodes. These devices are designed specifically for applications demanding accurate analog signal transfer while maintaining electrical isolation between input and output circuits.
