BC51-10PASX

Single Bipolar Transistors Overview

The BC51-10PASX is a PNP medium power transistor from the Nexperia BC51xPAS series, housed in an ultra-thin DFN2020D-3 (SOT1061D) leadless SMD plastic package. It features a maximum collector-emitter voltage of -45 V and a continuous collector current of -1 A, with a peak pulse current capability of -2 A. The device offers two DC current gain selections; the BC51-10PAS variant specifies a minimum hFE of 63 and a maximum of 160 at VCE = -2 V and IC = -150 mA. It includes an exposed heat sink for thermal management and is qualified to AEC-Q101 standards.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details such as reel size or tape width. Confirm that the component meets the required AEC-Q101 automotive reliability standards if intended for vehicle applications. Ensure the design accounts for the DFN2020D-3 package dimensions and thermal pad requirements during PCB layout.

Single Bipolar Transistors Selection Notes

Select this component when a compact PNP transistor with medium power handling is required in space-constrained designs. The BC51-10PAS variant provides a specific current gain range suitable for consistent amplification or switching performance. Consider the exposed thermal pad for effective heat dissipation on FR4 PCBs. Verify compatibility with automatic optical inspection processes due to the leadless package design.

Single Bipolar Transistors Part Context

This part belongs to the BC51xPAS series of PNP medium power transistors manufactured by Nexperia. The series utilizes the DFN2020D-3 package, which is designed for surface mounting with visible and solderable side pads. The family includes variants with different current gain selections to accommodate various circuit requirements while maintaining a standardized footprint and pinout configuration.

Single Bipolar Transistors Replacement Considerations

Direct substitutes within the same series include BC51PAS and BC51-16PAS, which share the same package and electrical ratings but differ in current gain specifications. Cross-family replacements require verification of pinout compatibility, voltage ratings, and thermal characteristics.
