IL211AT

Transistor, Photovoltaic Output Optoisolators Overview

The IL211AT is a single-channel optocoupler featuring a Gallium Arsenide infrared LED and an NPN silicon phototransistor. It provides a minimum current transfer ratio of 20% and supports a maximum forward current of 60 mA. The device offers an isolation voltage of 2500 VAC RMS and operates within a temperature range of -55°C to +100°C. Packaged in an SOIC-8 surface-mount format, it ensures reliable signal transmission with low dark current.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Integrates a GaAs infrared LED with an NPN phototransistor for optical coupling
• Provides high current transfer ratio performance starting at 20% minimum
• Supports standard reflow soldering processes including dual wave and vapor phase

Transistor, Photovoltaic Output Optoisolators Applications

• General purpose signal isolation
• DC level shifting circuits
• Logic interface applications

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific manufacturer origin, as documentation references both Infineon/Siemens and Vishay Semiconductor Opto Division. Confirm the package type matches the required SOIC-8 dimensions and ensure the suffix 'T' indicates tape and reel packaging if automated assembly is intended. Cross-reference UL recognition file numbers for compliance requirements.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a minimum 20% current transfer ratio is sufficient for the application logic levels. The SOIC-8 package facilitates surface mount integration. Ensure the 30 V collector-emitter breakdown voltage meets the load requirements. Verify that the 2500 VAC isolation rating aligns with safety standards for the target circuit environment.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the IL21xAT series, which includes variants with higher current transfer ratios such as the IL212AT (50%) and IL213AT (100%). All members share the same physical package and basic electrical structure but differ in gain specifications. The series is designed for surface mount applications requiring compact isolation solutions.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include IL212AT and IL213AT from the same family, offering higher current transfer ratios. Other compatible options may include MOC211R1VM, though pinout and electrical characteristics must be verified against the specific design requirements.
