BCP52-16

Overview

The BCP52-16 is a silicon epitaxial planar PNP medium voltage transistor housed in a SOT-223 plastic surface-mount package. It supports a continuous collector current of -1 A and peak currents up to -1.5 A, with maximum collector-emitter and collector-base voltages rated at -60 V. The device provides a total power dissipation capability of 1.4 W at 25°C ambient temperature. Electrical characteristics include a minimum DC current gain (hFE) ranging from 25 to 250 depending on the collector current level, and a transition frequency (fT) of 50 MHz.

Feature Summary

• Designed for high-current applications with low collector-emitter saturation voltage
• Utilizes a SOT-223 plastic package suitable for surface mounting circuits
• Complements the NPN BCP55-16 transistor type

Applications

• Medium voltage load switch transistors
• Output stage for audio amplifier circuits
• Automotive post-voltage regulation

Procurement Notes

Verify component authenticity through official STMicroelectronics channels or authorized distributors. Confirm that the specific ordering code matches the required specifications. Check for any obsolescence notices as this product may be subject to lifecycle changes. Ensure compliance with RoHS directives if environmental requirements are applicable to your design.

Selection Notes

Select this component when a PNP transistor with a -60 V rating and 1 A continuous current capacity is required. Consider the thermal resistance of 89.3 °C/W for heat dissipation planning. Verify that the SOT-223 package dimensions fit the PCB layout constraints. Ensure the operating junction temperature remains within the specified -65 to 150 °C range.

Part Context

This transistor belongs to the BCP series of low-power PNP-NPN complementary pairs. It is specifically designed for general-purpose switching and amplification tasks where medium voltage handling is necessary. The SOT-223 package offers a balance between power handling and compact surface-mount footprint.

Replacement Considerations

The NPN complementary type is the BCP55-16. For direct replacement, verify pinout compatibility and ensure electrical ratings meet or exceed the original requirements.
