PBSS4032NZ-QX

Single Bipolar Transistors Overview

The PBSS4032NZ is an NPN low VCEsat transistor manufactured by Nexperia USA Inc., housed in a medium power SOT223 (SC-73) surface-mounted device plastic package. It features a collector-emitter voltage of 30 V and a continuous collector current capability of 4.9 A, with a peak single-pulse collector current of 10 A. The device exhibits a typical collector-emitter saturation resistance of 45 mΩ at 4 A collector current and 400 mA base current. Total power dissipation reaches up to 2000 mW on an FR4 PCB with a standard footprint, while the junction temperature maximum is rated at 150 °C.

Single Bipolar Transistors Procurement Notes

Verify that the specific part number PBSS4032NZ corresponds to the non-automotive qualified version as indicated in the datasheet revision history. Confirm that the ordering suffix matches the required packaging configuration. Ensure design specifications align with the absolute maximum ratings provided in the official Nexperia documentation before finalizing procurement orders.

Single Bipolar Transistors Selection Notes

Select this component when designing circuits requiring high current handling within a medium power surface-mount package. The low saturation resistance minimizes heat generation during conduction. Evaluate thermal performance against the specified derating curves for the intended PCB footprint. Consider the transition frequency and switching times if high-speed modulation is required in the application design.

Single Bipolar Transistors Part Context

This NPN transistor belongs to the PBSS4032 series from Nexperia. The PNP complement for this series is designated as PBSS4032PZ. The device utilizes the SC-73 (SOT223) package variant, which provides increased heatsink capabilities compared to smaller packages. It is distinct from automotive-qualified variants which carry specific suffixes and testing certifications.

Single Bipolar Transistors Replacement Considerations

The official PNP complement is PBSS4032PZ. Verify pinout compatibility and electrical parameters against existing designs when substituting components. Ensure the replacement device meets the same thermal and current requirements of the original circuit specification.
