BCX52-16,115

Overview

The BCX52-16,115 is a PNP medium power transistor from the BCX52 series, manufactured by Nexperia. It is housed in a SOT89 (SC-62) surface-mount plastic package with an exposed die pad for thermal management. The device supports a collector-emitter voltage of -60 V and a continuous collector current of -1 A. It features three DC current gain selections; the -16 suffix denotes a range of 100 to 250 at IC = -150 mA. Key electrical parameters include a peak collector current of -2 A, a transition frequency of 145 MHz, and a maximum power dissipation of 1.35 W on a 6 cm² copper pad. It is qualified to AEC-Q101 standards.

Feature Summary

• High current capability with an exposed heatsink for superior thermal conductivity
• Three distinct DC current gain selection groups for design flexibility
• Qualified for automotive applications under AEC-Q101 standards

Applications

• Linear voltage regulators
• High-side switches
• Battery-driven devices
• Power management circuits
• MOSFET drivers

Procurement Notes

Verify the specific ordering code suffix matches the required hFE binning, as the -16 designation indicates a gain range of 100-250. Confirm the package type is SOT89 and check for RoHS compliance status. Ensure the procurement channel provides official Nexperia documentation to validate the component's authenticity and automotive qualification status before integration into production designs.

Selection Notes

Select this component when a PNP medium power transistor with high current handling and robust thermal performance is required. The exposed pad design necessitates proper PCB copper area allocation to achieve specified power dissipation ratings. Consider the -16 gain bin if precise base drive control within the 100-250 range is critical for the amplifier or switching application.

Part Context

This part belongs to the BCX52 family of 60 V, 1 A PNP transistors. It serves as the PNP complement to the BCX55 NPN series. The BCX52 variant specifically utilizes the SOT89 package, distinguishing it from the BCP52 (SOT223) and BC52PA (SOT1061) variants within the same product data sheet.
