BC56-10PASTX

Single Bipolar Transistors Overview

The BC56-10PAST is an NPN medium power transistor from the Nexperia BC56PAST series, housed in a DFN2020D-3 (SOT1061D) leadless SMD package. It features a collector-emitter voltage of 80 V and a continuous collector current of 1 A. The device offers a peak collector current of 2 A and a DC current gain range of 63 to 160 at IC = 150 mA and VCE = 2 V. Thermal resistance from junction to ambient is 235 K/W in free air, reducing to 124 K/W with a 1 cm² collector pad. The transition frequency is 100 MHz.

Single Bipolar Transistors Procurement Notes

Verify the specific part number suffix against the manufacturer's latest documentation to confirm current gain binning and packaging details. Ensure design compliance with absolute maximum ratings, particularly regarding total power dissipation and junction temperature limits under varying ambient conditions. Confirm that the selected footprint matches the DFN2020D-3 outline dimensions provided in the official datasheet.

Single Bipolar Transistors Selection Notes

Select this component when a compact, leadless surface-mount solution is required for medium power applications. The exposed heat sink design facilitates efficient thermal management compared to standard packages. Consider the specific hFE bin (BC56-10PAST vs. BC56PAST or BC56-16PAST) based on circuit gain requirements. Evaluate thermal resistance values relative to the intended PCB copper area to ensure safe operating temperatures.

Single Bipolar Transistors Part Context

This device belongs to the BC56PAST series, which includes complementary PNP transistors such as the BC53PAST. The series utilizes the DFN2020D-3 package, designed for automated optical inspection and high thermal performance. It serves as a modern replacement for older through-hole or larger surface-mount BJT technologies in space-constrained designs.

Single Bipolar Transistors Replacement Considerations

Direct functional substitutes within the same series include BC56PAST and BC56-16PAST, differing primarily in DC current gain ranges. For pin-compatible alternatives, verify package dimensions and thermal characteristics carefully.
