MPS3646G

Single Bipolar Transistors Overview

The MPS3646G is an NPN silicon small-signal transistor manufactured by onsemi. It is housed in a TO-92 (CASE 29-11) three-pin package. The device is rated for a collector current of 0.3A and a collector-emitter breakdown voltage of 15V. It is designed for general-purpose amplification and switching applications in low-power electronic circuits.

Single Bipolar Transistors Procurement Notes

Verify the manufacturer marking matches onsemi specifications. Confirm the package type is TO-92. Check datasheet revisions for electrical parameter updates. Ensure the component meets required thermal and voltage ratings for the specific application environment before integration.

Single Bipolar Transistors Selection Notes

Select this component for applications requiring a standard NPN small-signal transistor with 15V breakdown and 300mA current capacity. Consider the TO-92 package constraints for board space. Compare against other NPN transistors if higher voltage or current ratings are needed. Verify compatibility with existing circuit biasing requirements.

Single Bipolar Transistors Part Context

The MPS3646 series includes variants such as MPS3646C and MPS3646RLRM. These parts share similar NPN characteristics but may differ in packaging or specific manufacturer sourcing. The MPS3646G specifically denotes the onsemi version in the TO-92 case style, distinct from surface-mount or alternative package options found in the broader family.

Single Bipolar Transistors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with generic NPN transistors like 2N3904 only if electrical parameters align and package differences are acceptable.
