BCX17TA

Overview

The BCX17TA is a PNP bipolar junction transistor manufactured by Diodes Incorporated, designed for surface mount applications. It features a maximum collector-emitter breakdown voltage of 45V and a continuous collector current rating of 500mA. The device utilizes silicon technology and is housed in an SOT-23-3 package. Key electrical characteristics include a DC current gain (hFE) ranging from 100 to 300 at specific test conditions, a transition frequency (fT) of 100MHz, and a power dissipation capability of 330mW. The component supports a wide operating temperature range from -55°C to +150°C.

Feature Summary

• Single PNP configuration optimized for general-purpose switching and amplification tasks
• High current handling capability with 500mA continuous collector current rating
• Robust thermal performance supporting operation up to 150°C junction temperature

Applications

• General-purpose signal amplification circuits
• Low-power switching applications in consumer electronics
• Interface drivers within industrial control systems

Procurement Notes

Verify the obsolete status and End-of-Life (EOL) designation before procurement planning. Confirm availability through authorized distributors or surplus channels as standard production may be discontinued. Ensure compatibility with existing PCB footprints and reflow soldering profiles specified for the SOT-23-3 package. Request updated lifecycle documentation to assess long-term supply chain risks for ongoing projects.

Selection Notes

Select this component for designs requiring a compact PNP transistor with moderate current capacity. Compare hFE ranges against circuit requirements to ensure sufficient gain. Consider the 45V voltage limit when designing for higher voltage environments. Evaluate thermal management needs given the 330mW dissipation limit in the small outline package.

Part Context

This part belongs to the discrete semiconductor product category, specifically within the single bipolar transistors sub-family. Diodes Incorporated produces this component using standard silicon planar processes. The BCX17TA serves as a complementary device to NPN counterparts in the same series, providing balanced design options for push-pull configurations.

Replacement Considerations

Direct substitutes include other PNP transistors in SOT-23-3 packages with similar voltage and current ratings, such as the BCX16TA or BCY70 variants. Verify pinout compatibility and thermal resistance values when cross-referencing datasheets from different manufacturers.
