Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm the exact hFE binning grade required for your design. Confirm that the SC-70 footprint matches your PCB layout constraints. Ensure thermal management strategies account for the specified power dissipation limits under your operating conditions.

Single Bipolar Transistors Selection Notes

Select this component when a compact NPN transistor with moderate current handling is needed. The high-gain variant suits amplification tasks requiring precise control. Compare against the PNP complement 2PB1219A if complementary pairs are necessary for push-pull configurations or differential stages in low-power systems.

Single Bipolar Transistors Part Context

This part belongs to the 2PD1820A series of NPN transistors designed for general-purpose use. It replaces legacy components from the former NXP Standard Product business. The SOT323 package allows for automated assembly in consumer electronics manufacturing lines requiring small form factors.

Single Bipolar Transistors Replacement Considerations

The datasheet identifies the 2PB1219A as the PNP complement. Verify pinout compatibility and electrical characteristics before substituting with other SC-70 NPN transistors from different manufacturers.
