Overview
The BCP51TA is a PNP medium power transistor manufactured by Diodes Incorporated, housed in an SOT-223 surface-mount package. It features a maximum continuous collector current of -1 A and a peak pulse current of -2 A. The device supports a collector-emitter breakdown voltage (BVCEO) of -45 V and a collector-base breakdown voltage (BVCBO) of -45 V. Power dissipation reaches 2 W at +25°C ambient temperature. The transition frequency (fT) is specified at 150 MHz under standard test conditions.
Feature Summary
- Qualified to AEC-Q101 standards for high reliability applications
- Low saturation voltage performance with VCE(sat) less than -500 mV at -0.5 A
- Totally lead-free and fully RoHS compliant construction
- Halogen and antimony free "Green" device composition
Applications
- Medium power switching circuits
- Amplification stages
- Audio frequency driver sections
- Audio frequency output stages
Procurement Notes
Verify the specific ordering suffix against official Diodes Incorporated documentation to confirm packaging quantity and reel specifications. Ensure compliance requirements match project needs, as the TA suffix indicates tape and reel packaging. Confirm that the component meets all relevant environmental directives before final procurement integration.
Selection Notes
Select this component when a PNP transistor with -45 V collector-emitter voltage rating is required. The SOT-223 package provides adequate thermal dissipation for up to 2 W power handling. Consider the gain group availability if specific hFE ranges are necessary for the circuit design. Verify compatibility with complementary NPN types such as the BCP54 series.
Part Context
This part belongs to the BCP51/52/53 family of PNP medium power transistors designed for general-purpose amplification and switching tasks. The BCP51 variant specifically offers -45 V ratings, distinguishing it from higher voltage siblings like the BCP52 (-60 V) and BCP53 (-80 V). All variants share identical physical dimensions and pin configurations within the SOT-223 housing.
Replacement Considerations
Complementary NPN types include BCP54, BCP55, and BCP56. Other manufacturers produce equivalent parts such as the Nexperia BCP51-16,135. Verify electrical parameters and package dimensions before substitution.
