Single Bipolar Transistors Procurement Notes

Verify the specific suffix or packaging variant against the official datasheet before ordering, as physical dimensions and terminal arrangements may vary between production batches. Confirm that the component meets the required environmental standards for your specific assembly process. Ensure compatibility with the paired NPN device if used in complementary pairs. Check for any obsolescence notices from the manufacturer regarding long-term supply availability.

Single Bipolar Transistors Selection Notes

Select this component when a high-voltage PNP transistor is required to match the 2SC4381/4382 series. Consider the -150 V breakdown voltage and -2 A current capacity for load requirements. Evaluate the thermal resistance characteristics relative to the heatsinking strategy employed in the design. Ensure the operating frequency remains within the specified limits for the intended application speed.

Single Bipolar Transistors Part Context

This transistor belongs to the general-purpose discrete semiconductor category manufactured by Sanken Electric USA Inc.
