Single Bipolar Transistors Procurement Notes

Verify the specific hFE rank (R or S) required for your design, as the datasheet defines distinct gain ranges for each classification. Confirm that the SOT-323 package dimensions align with your PCB footprint constraints. Ensure thermal management strategies account for the 200mW power dissipation limit under expected operating conditions.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with a -120V breakdown voltage is necessary within a compact SOT-323 form factor. It is suitable for designs requiring a transition frequency up to 140MHz. Consider the complementary relationship with the 2SC4102U3 if symmetrical signal processing is required.
