Single Bipolar Transistors Procurement Notes

Verify component obsolescence status before procurement as the datasheet explicitly marks this series as obsolete and not recommended for new designs. Confirm that existing inventory meets all electrical specifications, particularly the 450 V collector-emitter voltage and 4 A continuous current ratings. Ensure thermal management solutions account for the specified junction-to-case thermal resistance and maximum operating temperature limits.

Single Bipolar Transistors Selection Notes

Select this component only for legacy system maintenance or repair where original specifications must be strictly maintained. Evaluate alternative modern transistors if designing new equipment due to the obsolete status. Consider the TO-220 mounting requirements and verify that the 1000 V blocking capability aligns with the circuit's peak voltage demands.

Single Bipolar Transistors Part Context

This part belongs to the TIPL791 series of NPN silicon power transistors manufactured by Bourns Inc. The series includes variants such as the TIPL791, which differs primarily in its lower voltage ratings compared to the TIPL791A. These components were designed for general-purpose high-voltage switching applications utilizing rugged planar technology.

Single Bipolar Transistors Replacement Considerations

The datasheet identifies the TIPL791A-S as obsolete. No specific substitute part numbers are provided in the official documentation. Designers should consult manufacturer catalogs for modern equivalents offering comparable voltage and current ratings.
