BC53-16PAST-QX

Single Bipolar Transistors Overview

The BC53-16PAST-QX is a PNP medium power transistor from the BC5xPAS-Q series, manufactured by Nexperia. It utilizes an ultra-thin DFN2020D-3 (SOT1061D) leadless surface-mount package with an exposed thermal pad. The device supports a maximum collector-emitter voltage of -80 V and a continuous collector current of -1 A. It features a minimum DC current gain (hFE) of 40 and a transition frequency (fT) of 145 MHz. The component is qualified to AEC-Q101 standards for automotive reliability and operates within a temperature range of -55°C to +150°C.

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'QX' against official Nexperia documentation to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the ordering part number matches the required hFE binning and that the DFN2020D-3 package variant aligns with the target PCB land pattern. Confirm RoHS compliance status through the manufacturer's restricted substances declaration.

Single Bipolar Transistors Selection Notes

Select this component when a compact, thermally efficient PNP transistor is required for automotive environments. The exposed pad design necessitates careful PCB thermal relief planning. Compare the -80 V rating against system voltage peaks. Verify that the SOT1061D footprint fits the assembly constraints compared to larger packages like SOT-223 or SOT-89.

Single Bipolar Transistors Part Context

This part belongs to the BC5xPAS-Q family, which includes variants with different voltage ratings such as the BC51PAS-Q (-45 V) and BC52PAS-Q (-60 V). All members share the same ultra-thin DFN2020D-3 package and automotive-grade reliability profile, allowing for design flexibility within the same form factor.

Single Bipolar Transistors Replacement Considerations

Direct pin-compatible replacements within the same package include other BC5xPAS-Q variants like BC52PAS-Q or BC51PAS-Q if lower voltage ratings are acceptable. Cross-manufacturer equivalents in the SOT1061D package require verification of thermal resistance and hFE characteristics.
