Single Bipolar Transistors Procurement Notes

Verify the specific hFE bin by checking the marking code on the component body; the suffix 'O' indicates a gain range of 70–140. Confirm the '-TP' suffix corresponds to the Tape & Reel packaging format containing 3,000 pieces per reel. Ensure compliance requirements such as RoHS or Halogen-Free status are met by verifying the presence of appropriate suffixes like '-HF' if required by your design specifications.

Single Bipolar Transistors Selection Notes

Select this component when a low-power NPN transistor with moderate current handling is required for compact designs. The SOT-23 package suits space-constrained PCB layouts. Consider the 'O' ranking if a guaranteed minimum gain of 70 is sufficient, whereas higher gain requirements may necessitate selecting different ranking suffixes available within the same series.

Single Bipolar Transistors Part Context

This part belongs to Micro Commercial Components' line of small-signal NPN transistors. It utilizes a standard SOT-23 surface-mount package, providing a balance between thermal performance and board space efficiency. The device is intended for general electronic equipment where reliable switching and amplification are needed under standard operating conditions.

Single Bipolar Transistors Replacement Considerations

Cross-reference with other NPN transistors in the SOT-23 package having similar VCEO and IC ratings. Verify that replacement parts meet the required hFE gain range and fT specifications to ensure circuit compatibility without redesigning bias networks.
