BCP51-16-QX

Overview

The Nexperia BCP51-16-QX is a PNP medium power transistor from the BCP51-Q series, housed in a SOT223 (SC-73) surface-mounted plastic package. It supports a collector-emitter voltage of -45 V and a continuous collector current of -1 A, with a peak pulse current capability of -2 A. The device features three current gain selections; the BCP51-16 variant specifies a DC current gain range of 100 to 250 at VCE = -2 V and IC = -150 mA. Qualified under AEC-Q101 for automotive applications, it operates across an ambient temperature range of -55 °C to 150 °C.

• High power dissipation capacity within a compact leadless package

Applications

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

Procurement Notes

Verify the specific ordering suffix matches the required gain bin, as the BCP51-16 designation indicates a specific hFE range. Confirm the package type corresponds to the SOT223 footprint requirements for your PCB layout. Ensure the component status aligns with production availability rather than development or preliminary stages before finalizing supply agreements.

Selection Notes

Select this component when designing circuits requiring robust PNP switching or amplification in space-constrained environments. The SOT223 package provides enhanced thermal performance compared to smaller SMD packages due to its exposed heatsink design. Consider the specific hFE bin required by your base drive circuitry, as the -16 suffix denotes a higher gain range suitable for efficient driver applications.

Part Context

This part belongs to the BCP51-Q series of PNP medium power transistors manufactured by Nexperia. The series shares identical electrical characteristics and pinouts but differs in current gain specifications. The BCP51-16 variant offers a gain range of 100 to 250, distinguishing it from the lower gain BCP51-10 and standard BCP51-Q variants within the same family.

Replacement Considerations

Direct substitutes include other BCP51-Q series variants such as BCP51-10-Q or BCP51-Q if the specific gain bin is not critical. Verify that any replacement maintains the SOT223 package outline and AEC-Q101 qualification if automotive reliability is required.
