BCP53-16HE3-TP

Overview

The BCP53-16HE3-TP is a PNP medium power transistor manufactured by Micro Commercial Components (MCC). It belongs to the BCX53 series and utilizes a SOT-89 surface-mount package. The device features a maximum collector current of 1 A and a collector-emitter breakdown voltage of 80 V. Key electrical characteristics include a DC current gain (hFE) minimum of 100 at 150 mA and 2 V, a transition frequency of 50 MHz, and a maximum power dissipation of 500 mW. The operating junction temperature range extends from -55°C to +150°C.

Feature Summary

• PNP medium power transistor configuration for signal amplification
• High DC current gain ensuring efficient control performance
• Robust thermal stability with wide operating temperature range
• Surface-mount SOT-89 packaging for compact circuit integration

Applications

• Audio amplifier circuits
• Linear voltage regulator designs
• General-purpose switching applications

Procurement Notes

Verify the specific datasheet version for the BCP53-16HE3-TP to confirm exact pinout configurations and absolute maximum ratings before finalizing the design. Ensure that the selected supplier provides documentation confirming RoHS compliance and lead-free manufacturing standards as indicated by the HE3 suffix. Cross-reference the manufacturer's official specifications against any third-party distributor data sheets to prevent discrepancies in critical parameters such as hFE grouping or thermal resistance values.

Selection Notes

Select this component when a PNP transistor with an 80 V collector-emitter voltage rating and 1 A continuous current capability is required. The SOT-89 package offers a balance between power handling and board space efficiency compared to larger through-hole options. Consider the 50 MHz transition frequency for applications requiring moderate speed. Verify that the thermal management strategy supports the 500 mW power dissipation limit under expected operating conditions.

Part Context

This part is part of the BCX53 series from MCC, which includes complementary NPN variants like the BCX54. The series is designed for general-purpose medium power applications. The HE3 suffix typically denotes environmental compliance features, specifically halogen-free construction and lead-free terminals, aligning with modern electronic manufacturing standards.

Replacement Considerations

Direct substitutes may include other manufacturers' PNP transistors in SOT-89 packages with similar 80V/1A ratings, such as the BCX53 from Diodes Incorporated or Nexperia. Ensure pin compatibility and equivalent hFE ranges are verified before substitution.
