BC51-16PA,115

Single Bipolar Transistors Overview

The BC51-16PA,115 is a PNP medium power transistor from the BC51 series manufactured by Nexperia. It utilizes an ultra-thin SOT1061 (HUSON3) leadless surface-mounted device plastic package with dimensions of 2 x 2 x 0.65 mm. The component supports a collector-emitter voltage (VCEO) of -45 V and a continuous collector current (IC) of -1 A. It features three DC current gain (hFE) selection groups: -10 (63-160), -16 (100-250), and general (63-250). The device has a maximum total power dissipation of 0.42 W at 25°C on a standard FR4 PCB and is qualified to AEC-Q101 standards.

Single Bipolar Transistors Procurement Notes

Verify the specific hFE selection group required for the application, as the -16 suffix denotes a gain range of 100 to 250. Confirm the SOT1061 package compatibility with the target PCB footprint, noting the leadless HUSON3 design requires specific soldering considerations. Ensure the operating conditions remain within the absolute maximum ratings defined in the datasheet to prevent permanent damage.

Single Bipolar Transistors Selection Notes

Select this component when a compact PNP transistor with high current handling is needed in space-constrained designs. The SOT1061 package offers superior thermal performance compared to standard small outlines due to its exposed pad. Consider the specific hFE bin (-16) if tight gain control is necessary. Verify that the 45 V voltage rating meets the circuit's maximum collector-emitter requirements.

Single Bipolar Transistors Part Context

This part belongs to the BC51 series of PNP medium power transistors, which also includes the BCP51 and BCX51 variants. While sharing similar electrical characteristics, these parts differ primarily in their physical packaging. The BC51PA specifically utilizes the SOT1061 package, distinguishing it from the leaded SOT89 or larger SOT223 options found in the same product family.
