Single Bipolar Transistors Procurement Notes

Verify the specific manufacturer origin, as Intersil acquired Harris Semiconductor assets. Confirm the exact suffix code matches the required voltage rating variant, as similar part numbers exist with different breakdown voltages. Ensure the TO-220AB package dimensions align with your board layout requirements before finalizing procurement.

Single Bipolar Transistors Selection Notes

Select this component when high voltage blocking capability combined with moderate current handling is required. The TO-220AB package facilitates direct mounting to heatsinks. Consider the 350V rating for safety margins in primary-side switching applications. Verify that the 8A continuous current rating meets the peak load demands of the target circuit design.

Single Bipolar Transistors Part Context

This component belongs to the Harris Corporation line of discrete power transistors. It is functionally related to the 2N6738, which shares the same current rating but offers a lower 300V breakdown voltage. Both devices utilize the same TO-220AB plastic epoxy package and are designed for general-purpose power switching applications in industrial and consumer electronics.

Single Bipolar Transistors Replacement Considerations

The 2N6738 is a compatible alternative if the application voltage does not exceed 300V. Verify pinout compatibility and thermal resistance characteristics when substituting. Ensure the replacement part meets the same NPN polarity and silicon material specifications.
