Overview
The BCP51-16,115 is a PNP medium power transistor from Nexperia, housed in an SOT223 (SC-73) surface-mount package. It features a collector-emitter voltage of -45 V and a continuous collector current of -1 A. The device supports a peak collector current of -2 A for single pulses up to 1 ms. DC current gain (hFE) ranges from 100 to 250 at IC = -150 mA and VCE = -2 V. Total power dissipation reaches 1.35 W on an FR4 PCB with a 6 cm² collector pad. Transition frequency is typically 145 MHz.

Procurement Notes
Verify the specific ordering suffix matches the required tape-and-reel configuration. Confirm the hFE selection group corresponds to the design requirements. Ensure the component status aligns with current production data sheets before finalizing procurement specifications.
Selection Notes
Select this component for applications requiring robust PNP switching or amplification in compact surface-mount layouts. The SOT223 package offers improved thermal performance compared to smaller alternatives. Consider the specific hFE binning needs when designing biasing networks for consistent gain across operating temperatures.
Part Context
This part belongs to the BCX51/BCP51/BC51PA series of PNP medium power transistors. It serves as the PNP complement to the NPN BCX54/BCP54/BC54PA family. The series provides standardized pinouts and electrical characteristics for interchangeable use in various power management and signal processing designs.
Replacement Considerations
BCP54 is the direct NPN complement within the same series. Other PNP transistors with similar -45V/-1A ratings may require verification of pinout compatibility and thermal resistance values.
