Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix designation when ordering, as it determines the packaging format and compliance status. Confirm that the 2500 Vrms isolation rating meets the safety requirements of the target application. Ensure compatibility with standard DIP-8 footprint dimensions during PCB layout. Check for lead-free compliance if required by regional regulations.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component for applications requiring moderate speed isolation up to 1 Mbps. Consider the 8 mA collector current limit when designing pull-up resistor networks. Evaluate the thermal performance given the 100 °C maximum operating temperature. Compare against newer equivalents like the HCPL253xM series if new design recommendations are strictly followed.

Transistor, Photovoltaic Output Optoisolators Part Context

The HCPL2531V belongs to the HCPL-2531 family of dual-channel high-speed optocouplers. This series is part of onsemi's portfolio of logic IC output optocouplers designed for reliable digital signal transmission. It shares architectural similarities with single-channel variants like the 6N135 but offers integrated dual-channel functionality in a single package.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

The manufacturer recommends using the HCPL253xM series as the new equivalent part number for this component. Verify pinout compatibility and electrical specifications before substituting with other dual-channel optocouplers.
