BCX53TX

Overview

The Nexperia BCX53TX is a PNP power bipolar transistor housed in a SOT-223 (SC-73) surface-mount package. It features a maximum collector current of -1 A and a collector-emitter voltage rating of -80 V, with a collector-base voltage of -100 V. The device supports a maximum power dissipation of 1.35 W and has a transition frequency of 145 MHz. It operates within a temperature range of -55°C to +150°C and meets AEC-Q101 automotive qualification standards.

Feature Summary

• High collector current capability for robust switching performance
• Qualified for automotive applications under AEC-Q101 standards
• Designed for high-power dissipation in compact surface-mount packages

Applications

• Linear voltage regulators
• MOSFET drivers
• High-side switches
• Power management circuits
• Amplifiers

Procurement Notes

Verify the specific suffix 'TX' against the official Nexperia datasheet to confirm tape-and-reel packaging specifications. Ensure the selected variant matches the required current gain binning for your circuit design. Confirm RoHS compliance status and lead-free soldering compatibility prior to final procurement approval.

Selection Notes

Select this component when a PNP transistor with 1 A continuous current handling is required in a SOT-223 footprint. Consider the -80 V breakdown voltage for medium-voltage applications. Verify thermal management requirements given the 1.35 W dissipation limit in the specified package style.

Part Context

This part belongs to the BCX53 series of PNP power transistors from Nexperia. It serves as the PNP counterpart to the NPN BCX54 series. The SOT-223 package provides a balance between power handling and board space efficiency compared to larger through-hole alternatives.

Replacement Considerations

The BCP53-16TX is a direct functional substitute within the same family, sharing identical electrical ratings and SOT-223 packaging. Verify pinout compatibility before substitution.
