BC51-16PASX

Single Bipolar Transistors Overview

The BC51-16PASX is a PNP medium power transistor from the BC51xPAS series, encapsulated in an ultra-thin DFN2020D-3 (SOT1061D) leadless SMD plastic package. It features a collector-emitter voltage (VCEO) of -45 V and a continuous collector current (IC) of -1 A, with a peak pulse current (ICM) of -2 A. The device offers a DC current gain (hFE) range of 100 to 250 at VCE = -2 V and IC = -150 mA. It includes an exposed heat sink for thermal conductivity and is AEC-Q101 qualified.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix 'SX' against the official Nexperia datasheet or distributor documentation to confirm reel packaging specifications. Ensure the component matches the BC51-16PAS type number with marking code C6. Confirm AEC-Q101 qualification status if used in automotive designs. Check the most recent product data sheet for any specification updates before finalizing procurement.

Single Bipolar Transistors Selection Notes

Select this component when a compact PNP transistor with high current handling is required in space-constrained designs. The DFN2020D-3 package provides a balance between medium power capability and minimal PCB area. Consider the hFE selection of 100-250 for consistent gain performance. Evaluate thermal resistance requirements based on the specific PCB copper layer configuration and mounting pad size.

Single Bipolar Transistors Part Context

This part belongs to the BC51xPAS series, which includes variants like BC51PAS, BC51-10PAS, and BC51-16PAS. All share the same DFN2020D-3 package and general electrical characteristics but differ in current gain ranges. The series replaces older packages with a leadless design offering improved thermal performance and suitability for automated assembly processes.

Single Bipolar Transistors Replacement Considerations

BC51-10PAS offers a lower current gain range (63-160). BC51PAS provides a wider gain range (63-250). Both use the identical DFN2020D-3 package and electrical ratings. Verify that the specific gain bin required by the circuit design matches the replacement variant's specifications.
