H11A2XG

Transistor, Photovoltaic Output Optoisolators Overview

The H11A2XG is a single-channel optoisolator manufactured by onsemi, distributed by Isocom Components. It features an infrared LED input and a phototransistor output with a base terminal for enhanced switching control. The device provides high isolation capability of 5300Vrms and supports a maximum forward current of 60 mA. It operates within a temperature range of -40°C to 100°C and is housed in a standard 6-DIP package.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Phototransistor output includes a dedicated base pin to facilitate faster turn-off times and improved noise immunity compared to standard configurations.
• Provides robust electrical isolation between input and output circuits with a rated voltage of 5300Vrms.
• Designed for through-hole mounting in a 6-pin DIP configuration suitable for general-purpose digital signal isolation.

Transistor, Photovoltaic Output Optoisolators Applications

• Digital signal isolation in microprocessor systems
• Gate drive isolation for power switching devices
• Solid-state relay driver circuits

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the manufacturer designation carefully, as the component is produced by onsemi but often listed under Isocom Components in distributor catalogs. Confirm the specific suffix requirements for tape-and-reel versus tube packaging if automated assembly is intended. Check for end-of-life status or alternative sourcing options due to potential supply chain variations.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when base-controlled transistor output is required for faster switching performance than standard phototransistors offer. Ensure the application voltage does not exceed the 30V collector-emitter rating. Verify that the 6-DIP footprint matches the PCB layout constraints and that the 5300Vrms isolation level meets the safety standards of the target system.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the H11A series of optocouplers, which are widely used for general-purpose isolation. The H11A2 variant specifically denotes the transistor-with-base output type, distinguishing it from variants like H11A1 (Darlington) or H11A3 (standard transistor). It is a legacy component often replaced by newer series such as HCPL-2631 or similar modern equivalents.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct replacements include the H11A2M (surface mount) or H11A2L (lead-free). For functional equivalence with base output, consider the HCPL-2631 or IL300 series, though pinouts and CTR specifications may differ. Always verify thermal and electrical ratings before substitution.
