Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix 'VL' against official Nexperia documentation to confirm availability and exact marking codes. Ensure the procurement channel sources genuine components matching the provided data sheet specifications. Confirm that the delivered parts align with the stated automotive qualification status and package dimensions.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring a compact NPN switching solution with automotive-grade reliability. The 200 mA current rating and 40 V breakdown voltage suit general signal processing tasks. Consider the thermal resistance and power dissipation limits when designing heat management strategies for dense PCB layouts.

Single Bipolar Transistors Part Context

This part belongs to the MMBT3904 series of small-signal NPN transistors. The PNP complement is the MMBT3906. The device utilizes a standard three-terminal SOT-23 configuration with pin assignments for base, emitter, and collector. It is designed for high-volume manufacturing and integration into modern electronic assemblies.

Single Bipolar Transistors Replacement Considerations

The MMBT3906 serves as the complementary PNP device within the same family. Verify pinout compatibility and electrical parameters when substituting with other generic NPN transistors to ensure equivalent saturation voltages and switching speeds.
