BCP49H6359XTMA1

Overview

The BCP49H6359XTMA1 is an NPN silicon Darlington transistor manufactured by Infineon Technologies. It features a collector-emitter voltage rating of 60 V and a continuous DC collector current capacity of 500 mA. The device operates with a high DC current gain (hFE) of up to 10,000 at IC = 100 mA. It has a maximum power dissipation of 1.5 W and a transition frequency of 200 MHz. The component is housed in a surface-mount PG-SOT223-4 package.

Feature Summary

• High current gain capability suitable for sensitive signal amplification
• Robust power handling with 1.5 W dissipation rating
• Surface-mount design for automated assembly integration

Applications

• Audio amplifier circuits
• RF amplifier stages
• Electronic switching applications

Procurement Notes

Verify the specific ordering suffix XTMA1 to ensure correct packaging configuration. Confirm that the PG-SOT223-4 package matches the target PCB footprint requirements. Check datasheet specifications for thermal management needs given the 1.5 W power rating. Ensure compatibility with the intended operating temperature range before finalizing procurement.

Selection Notes

Select this component when high current gain is required for driving loads with minimal input current. The 60 V rating suits low-voltage applications. Consider the SOT223-4 package for space-constrained designs. Evaluate thermal performance under load to ensure the 1.5 W dissipation limit is not exceeded in the final application environment.

Part Context

This part belongs to the BCP49 series of bipolar junction transistors from Infineon Technologies. It is designed as a single NPN Darlington pair. The series targets general-purpose amplification and switching tasks. The component integrates two transistors on a single die for enhanced gain characteristics compared to standard BJTs.

Replacement Considerations

Direct substitutes must match the NPN Darlington configuration, 60 V VCEO, 500 mA IC, and PG-SOT223-4 package. Verify pinout compatibility and thermal resistance values. Cross-reference hFE ranges to ensure equivalent amplification performance in the specific circuit design.
