HMHA2801R1 is listed in the Transistor, Photovoltaic Output Optoisolators range at ChipApex. The manufacturer field lists onsemi. Its product description is OPTOISO 3.75KV TRANS 4-MINI-FLAT. Review the specifications below when checking this part for your BOM.
The HMHA2801R1 is a single-channel transistor output optocoupler manufactured by onsemi. It features a 4-Mini-Flat surface-mount package with 3750Vrms isolation voltage. The device supports a maximum collector-emitter voltage of 80V and a continuous output current of 50mA. Typical rise and fall times are 3µs each. The Current Transfer Ratio ranges from 80% to 600% at a forward current of 5mA. Operating temperature spans -55°C to 100°C.
Verify the specific suffix R1 indicates tape and reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer declarations. Check for any recent Product Change Notifications regarding assembly or material updates. Ensure the supplier provides valid traceability documentation for quality assurance purposes.
Select this component for applications requiring moderate speed isolation with a small footprint. Compare CTR specifications against circuit requirements to ensure adequate noise margin. Verify that the 80V output voltage rating exceeds the load requirements. Consider thermal management within the specified operating temperature range during design integration.
This part belongs to the HMHA series of miniature optocouplers designed for high-density PCB layouts. It serves as a compact alternative to larger SOIC packages while maintaining similar electrical performance characteristics. The series is intended for general-purpose isolation tasks in consumer and industrial electronics.
HMHA2801AR1 is a related variant with different packaging options. Verify pinout compatibility and electrical parameters before substitution. Ensure the replacement part meets the same isolation voltage and current transfer ratio requirements.
