Single Bipolar Transistors Procurement Notes

Verify the authenticity of the MMBT4403HE3-TP by purchasing exclusively from Micro Commercial Components or their authorized distributors. Counterfeit components pose significant risks; unauthorized sources do not provide warranty coverage or traceability. Ensure the ordering suffix '-TP' corresponds to the tape and reel packaging configuration specified in the official documentation before finalizing procurement.

Single Bipolar Transistors Selection Notes

Select the MMBT4403HE3-TP when automotive qualification and environmental compliance are required. This part serves as the PNP counterpart to the NPN MMBT4401HE3-TP. Designers should account for the 350 mW power dissipation limit and the specific saturation voltages at varying collector currents. The SOT-23 package constrains thermal management strategies compared to larger packages.

Single Bipolar Transistors Part Context

This component belongs to the MMBT4403 series of PNP small-signal transistors produced by Micro Commercial Components. The HE3 designation indicates enhanced environmental specifications, specifically halogen-free composition and lead-free finish. The product line targets high-reliability markets, including automotive electronics, where strict adherence to quality standards like AEC-Q101 is mandatory.

Single Bipolar Transistors Replacement Considerations

The MMBT4401HE3-TP is the complementary NPN transistor within the same MCC family. Other manufacturers produce equivalent parts such as the MMBT4403 from onsemi or DiodesZetex, though electrical parameters and package dimensions may vary slightly.
