BC54-16PASX

Single Bipolar Transistors Overview

The BC54-16PASX is an NPN medium power transistor from the Nexperia BC54xPAS series, encapsulated in a DFN2020D-3 (SOT1061D) leadless SMD 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 DC current gain (hFE) ranges from 100 to 250 at IC = 150 mA and VCE = 2 V. Total power dissipation reaches 1.65 W at Tamb ≤ 25 °C on a standard FR4 PCB. The transition frequency (fT) is typically 180 MHz.

Single Bipolar Transistors Feature Summary

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm package type and gain binning. Confirm that the component is non-automotive qualified as per the datasheet revision history. Ensure compatibility with the specified DFN2020D-3 footprint and reflow soldering profiles during procurement planning.

Single Bipolar Transistors Selection Notes

Select this component for applications requiring high current density in a minimal footprint. The exposed pad design supports efficient thermal management without additional heatsinks in many scenarios. Verify that the required hFE range aligns with the BC54-16PAS variant specifications. Consider the 45 V rating when designing circuits with higher supply voltages or transient spikes.

Single Bipolar Transistors Part Context

This device belongs to the BC54xPAS series, which includes variants like BC54PAS and BC54-10PAS. All share the same DFN2020D-3 package and general electrical limits but differ in current gain bins. The series replaces older plastic packages with a leadless thermal-enhanced design suitable for modern surface-mount assembly processes.

Single Bipolar Transistors Replacement Considerations

Direct substitutes within the same series include BC54PAS and BC54-10PAS, differing primarily in DC current gain ranges. Cross-package replacements require verification of thermal resistance and pinout compatibility.
