Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix code against official datasheets to confirm current transfer ratio and packaging configuration. Ensure compatibility with required isolation standards and operating temperature ranges before integration. Confirm RoHS compliance status through manufacturer documentation. Validate pinout assignments for the PDIP-8 package during PCB layout to prevent installation errors.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when dual-channel isolation is required within a single footprint. Consider the 50 mA collector current limit and 70 V breakdown voltage for load matching. Evaluate the 18 us switching times for signal integrity requirements. Compare current transfer ratio specifications across variants to ensure adequate gain for the intended application logic levels.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the ACPL series of multi-channel full-pitch phototransistor optocouplers from Broadcom. The series is designed for general-purpose isolation applications where reliable signal transmission across potential differences is necessary. The W0BE suffix typically denotes specific binning or packaging variations within the broader product family.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Cross-reference with other ACPL-827 variants such as ACPL-827-50BE or ACPL-827-30BE for different current transfer ratios. Verify that substitute parts maintain identical pinouts and insulation voltage ratings. Check for equivalent package dimensions to ensure mechanical compatibility without PCB redesign.
