BCX5616E6433HTMA1

Overview

The BCX5616E6433HTMA1 is an NPN silicon audio frequency transistor from the BCX56 series, housed in a SOT89 surface-mount package. It features a maximum collector-emitter voltage of 80 V and a continuous collector current rating of 1 A. The device supports a peak collector current of 1.5 A with a total power dissipation of 2 W at case temperatures up to 120°C. Key electrical characteristics include a DC current gain ranging from 100 to 250 at 150 mA and a transition frequency of 100 MHz.

Feature Summary

• Designed for audio frequency driver and output stages
• High collector current capability with low saturation voltage
• Qualified according to AEC Q101 automotive standards

Applications

• Audio frequency driver stages
• Audio frequency output stages
• General-purpose amplification circuits

Procurement Notes

Verify the specific suffix '16' against official Infineon documentation to confirm the hFE binning range. Ensure the ordering code matches the exact voltage and gain specifications required for the target application. Confirm RoHS compliance and Pb-free status through the manufacturer's material content sheets.

Selection Notes

Select this component when high collector current and robust thermal performance are required in a compact SOT89 footprint. Consider the complementary BCX53 PNP type for push-pull configurations. Evaluate the thermal resistance and derating curves if operating near the maximum power dissipation limits.

Part Context

This part belongs to the BCX54/BCX55/BCX56 family of NPN silicon AF transistors. The BCX56 variant specifically offers higher voltage ratings compared to the BCX54 and BCX55 models. The family provides complementary PNP options (BCX51-BCX53) for balanced circuit designs.

Replacement Considerations

Official substitutes within the same family include BCX54-16 and BCX55-16, provided their lower voltage ratings meet the circuit requirements.
