Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix BR2 to confirm the tape-and-reel packaging configuration, as other suffixes may indicate bulk or cut-tape options. Confirm RoHS compliance status and check for any recent Product Change Notifications (PCN) regarding assembly location or material changes. Ensure the 4-Mini-Flat footprint matches the target PCB layout dimensions before finalizing procurement orders.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a compact form factor is required alongside high isolation voltage ratings. The Mini-Flat package offers space savings compared to standard SOIC packages while maintaining similar electrical performance. Consider the 3µs switching speed for applications requiring moderate data rates. Verify that the 80V collector-emitter voltage rating meets the load requirements of the isolated circuit side.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the HMHA series of transistor output optocouplers from onsemi. The series is characterized by the use of GaAs infrared LEDs and NPN phototransistors in small outline packages. The HMHA2801BR2 specifically denotes the version packaged in tape and reel format, distinguishing it from bulk variants like the HMHA2801.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct pin-compatible replacements within the same family include HMHA2801 (bulk) and HMHA281V. Cross-family comparisons should verify isolation voltage, CTR, and package dimensions. No other specific substitute part numbers are confirmed in public documentation.
