Single Bipolar Transistors Procurement Notes

Verify the specific manufacturer designation when sourcing, as historical data indicates Sanyo production while current listings associate the part with onsemi. Confirm the exact package variant matches the required PCB footprint. Ensure compatibility with existing thermal interface materials for the TO-3PB style. Cross-reference datasheet revisions to confirm electrical characteristics remain consistent with design requirements.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring moderate voltage blocking and high continuous current in a standard through-hole form factor. The TO-3PB package facilitates direct heatsink attachment for effective thermal dissipation. Consider the 50 V rating relative to circuit peak voltages. Evaluate the 90 W power limit against expected operating temperatures and ambient conditions to ensure safe operation margins.
