Single Bipolar Transistors Procurement Notes

Verify component authenticity by checking markings against the official diagram: 'C6145A' followed by lot number and hFE rank. Confirm package type is TO-3P-3L. Ensure compliance with RoHS requirements via bare lead frame verification. Check datasheet revision status before integration.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring high-voltage handling up to 260 V and substantial current capacity of 15 A. Consider the thermal resistance of 0.78 °C/W when designing heatsinking solutions. Verify that the application does not require aerospace or medical-grade reliability, as these are excluded from standard use cases.
