Single Bipolar Transistors Procurement Notes

Verify the manufacturer source carefully, as Harris Corporation's semiconductor assets were acquired. Ensure the specific lot date code aligns with your production timeline. Confirm that the TO-3 package dimensions match your thermal management design requirements before finalizing orders.

Single Bipolar Transistors Selection Notes

Select this component when high voltage blocking and substantial current drive are required in a single package. The Darlington structure simplifies base drive requirements compared to standard BJTs. Evaluate thermal resistance constraints given the 120W power rating and ensure adequate heatsinking for the TO-3 enclosure.

Single Bipolar Transistors Part Context

This discrete semiconductor belongs to the Bipolar (BJT) category, specifically Single Transistors. It serves as a fundamental active element in power electronics, distinct from integrated logic or linear ICs. Its classification emphasizes its role in direct current and signal amplification rather than complex digital processing.

Single Bipolar Transistors Replacement Considerations

Consult official cross-reference lists for equivalent NPN Darlington transistors with matching 400V/8A ratings. Verify pinout compatibility for the TO-3 package if substituting with parts from other manufacturers to ensure correct circuit integration.
