BC54-10PASX

Single Bipolar Transistors Overview

The BC54-10PASX is an NPN medium power transistor from the Nexperia BC54xPAS series, housed in a DFN2020D-3 (SOT1061D) leadless package. It supports a 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 features a DC current gain (hFE) range of 63 to 160 at IC = 150 mA and VCE = 2 V. Key electrical parameters include a collector-base cutoff current of 100 nA, a transition frequency of 180 MHz, and a total power dissipation up to 1.65 W depending on PCB mounting conditions.

Single Bipolar Transistors Feature Summary

• High collector current capability for both continuous and pulsed operations
• Exposed heat sink providing excellent thermal and electrical conductivity

Single Bipolar Transistors Procurement Notes

Verify that the specific BC54-10PASX part number corresponds to the non-automotive qualified version as defined in the October 2024 product data sheet revision. Confirm that the application environment does not require automotive qualification standards, as this specific variant lacks AEC-Q101 certification. Ensure design inputs align with the stated limiting values and thermal characteristics for the selected PCB footprint.

Single Bipolar Transistors Selection Notes

Select the BC54-10PASX when a compact, leadless surface-mount solution is required for medium power switching or amplification tasks. The DFN2020D-3 package offers reduced PCB area requirements compared to traditional packages while maintaining high current handling. Choose this specific gain bin (BC54-10PAS) if the circuit design requires a guaranteed hFE maximum of 160 at 150 mA collector current, distinguishing it from the standard BC54PAS variant.

Single Bipolar Transistors Part Context

This component belongs to the BC54xPAS series of NPN medium power transistors manufactured by Nexperia. The series utilizes an ultra-thin DFN2020D-3 package designed for high thermal performance and small form factor applications. The BC54-10PASX represents a specific current gain selection within this family, differentiated from other variants like the BC54-16PAS by its specified hFE range.
