HCPL0453R2

Transistor, Photovoltaic Output Optoisolators Overview

The HCPL0453R2 is a single-channel high-speed optocoupler from the HCPL series, manufactured by onsemi (formerly Fairchild Semiconductor). It features a DC input and logic output configuration housed in an 8-pin SOIC package. Key electrical parameters include a maximum forward voltage of 1.8V, a typical rise time of 5ns, and a data rate of 1 Mbps. The device offers an isolation voltage of 2500V AC and operates within a temperature range of -40°C to 85°C. Current transfer ratio specifications range from a minimum of 19% to a maximum of 50%, with a maximum input current of 25mA.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• High-speed signal transmission capability suitable for digital communication interfaces
• Logic output configuration providing direct compatibility with standard logic circuits
• Robust electrical isolation between input and output sections

Transistor, Photovoltaic Output Optoisolators Applications

• Digital communication interface isolation
• Industrial control system signal coupling
• Data acquisition systems requiring galvanic isolation

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the manufacturer designation carefully, as this component was originally produced by Fairchild Semiconductor and is now part of onsemi's portfolio. Ensure the specific suffix 'R2' matches your reel packaging requirements. Confirm that the 2500V AC isolation rating meets your safety standards compared to other variants in the HCPL family which may offer higher ratings.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a balance of moderate speed (1 Mbps) and cost-effectiveness is required for single-channel isolation. The 8-pin SOIC package facilitates surface-mount assembly. Consider the 19-50% current transfer ratio range for circuit design margins. Verify that the 85°C maximum operating temperature aligns with your thermal management strategy.

Transistor, Photovoltaic Output Optoisolators Part Context

This device belongs to the HCPL series of high-speed optocouplers. It represents the transition of Fairchild Semiconductor's optoelectronics division into onsemi. The HCPL0453 variant specifically targets applications needing reliable digital isolation without the complexity or cost of higher-speed gate driver optocouplers.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

HCPL-0453 is a related variant but typically uses tube packaging and may have different isolation ratings. HCPL0453R2V is another version; verify if the 'V' suffix indicates a specific tape-and-reel variation or environmental compliance difference before substituting.
