BCX53-TP

Overview

The BCX53-TP is a single PNP bipolar junction transistor manufactured by Micro Commercial Components. It features an 80 V maximum collector-emitter breakdown voltage and supports a continuous collector current of 1 A. The device operates with a transition frequency of 50 MHz and handles a maximum power dissipation of 500 mW. It is housed in a surface-mount SOT-89 package, also identified as TO-243AA, and functions within a junction temperature range of -55°C to 150°C.

Feature Summary

• PNP polarity configuration for complementary circuit designs
• Surface-mount SOT-89 packaging for automated assembly
• High thermal stability across extended industrial temperature ranges

Applications

• General-purpose switching circuits
• Complementary amplifier stages
• Driver applications requiring moderate current handling

Procurement Notes

Verify the specific manufacturer designation on the component marking, as the BCX53 series is produced by multiple vendors including Diotec Semiconductor. Confirm that the received part matches the required hFE binning and package type (SOT-89) specified in your design documentation before integration into production.

Selection Notes

Select this component when a PNP transistor with 80 V rating and 1 A current capacity is required in a compact surface-mount form factor. Ensure the application does not exceed the 500 mW power dissipation limit under worst-case thermal conditions. Verify compatibility with the specific hFE gain requirements of the target circuit topology.

Part Context

This component belongs to the BCX53 family of general-purpose PNP transistors. While the base model shares core electrical characteristics, suffixes such as -16 or -HE3 may indicate variations in gain grouping or environmental compliance. The -TP suffix typically denotes tape-and-reel packaging from Micro Commercial Components.

Replacement Considerations

BCX53-16 is a confirmed equivalent part number offering identical electrical specifications in the same SOT-89 package.
