BCX5316H6433XTMA1

Overview

Infineon BCX5316H6433XTMA1 is a PNP silicon audio frequency transistor in SOT-89 packaging. It features a collector-emitter voltage of 80 V, collector-base voltage of 100 V, and emitter-base voltage of 5 V. The device supports a continuous collector current of 1 A and peak current of 1.5 A. Total power dissipation reaches 2 W at case temperatures up to 120 °C. Junction temperature tolerance extends to 150 °C with storage limits from -65 °C to 150 °C. Transition frequency is typically 125 MHz.

Feature Summary

• Designed for audio driver and output stages
• High collector current capability
• Low collector-emitter saturation voltage

Applications

• Audio frequency driver stages
• Audio frequency output stages

Procurement Notes

Verify the specific suffix H6433XTMA1 against official Infineon documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with SOT-89 footprints during PCB layout. Confirm RoHS compliance status through the manufacturer's material content sheet before finalizing procurement orders.

Selection Notes

Select this component when an 80 V PNP transistor with 1 A continuous current rating is required. The low saturation voltage makes it suitable for efficient audio amplification circuits. Verify thermal management requirements as total power dissipation depends on case temperature constraints within the specified operating range.

Part Context

The BCX53 series represents PNP silicon transistors complementary to the BCX54...BCX56 NPN family. These devices are qualified according to AEC-Q101 standards for automotive applications. The BCX53 variant specifically offers higher voltage ratings compared to the BCX51 and BCX52 counterparts within the same product line.

Replacement Considerations

BCX53-16 serves as a direct functional replacement within the same series.
