BCP51-16-TP

Overview

The BCP51-16-TP is a PNP silicon epitaxial planar transistor in a SOT-223 package. It features a collector-emitter voltage (VCEO) of -45 V, a collector-base voltage (VCBO) of -45 V, and an emitter-base voltage (VEBO) of -5 V. The device supports a maximum collector current (IC) of -1 A and power dissipation (PD) of 1.5 W at 25°C. Thermal resistance from junction to ambient is 83.3°C/W. The transition frequency (fT) is 100 MHz. DC current gain (hFE) ranges from 100 to 250 for the -16 variant. Operating and storage temperatures span -55°C to +150°C.

Procurement Notes

Verify the specific suffix '-TP' indicates tape and reel packaging containing 2,500 pieces per reel, distinct from bulk or cut tape options. Confirm RoHS compliance status associated with the manufacturer's standard production run. Ensure sourcing channels are authorized distributors to guarantee genuine parts and full traceability. Check for any recent product change notices that might affect pinout or electrical characteristics.

Selection Notes

Select this component when a medium-power PNP transistor with high current capability is required in a surface-mount SOT-223 form factor. The -16 ranking provides a higher DC current gain range compared to the -10 variant. Consider the 1.5 W power dissipation limit and thermal resistance for heat management in the final design. Verify compatibility with complementary NPN devices if push-pull configurations are utilized.

Part Context

This part belongs to the BCP51 series of plastic-encapsulated transistors manufactured by Micro Commercial Components. It serves as the PNP counterpart to the BCP54 NPN transistor within the same family. The SOT-223 package allows for efficient surface mounting on printed circuit boards while providing adequate thermal performance for general-purpose switching and amplification applications.

Replacement Considerations

Direct replacements include the BCP51-16 from other manufacturers such as Nexperia or ON Semiconductor, provided pinouts and electrical ratings match. Verify that substitute parts maintain the same SOT-223 footprint and thermal characteristics. Cross-reference hFE binning requirements to ensure equivalent gain performance in the target circuit.
