Single Bipolar Transistors Procurement Notes

Verify the specific datasheet for the 2N3498U4 variant, as standard 2N3498 documentation often references through-hole TO-39 packages. Confirm the U4 package designation and surface-mount compatibility directly with Microchip Technology or authorized distributors. Ensure the ordering suffix matches the required SMD configuration distinct from the leaded versions.

Single Bipolar Transistors Selection Notes

Select this component when a surface-mount NPN transistor with 100V rating and 1W dissipation is required. The U4 package facilitates automated assembly. Verify that the application environment supports the specified operating temperature range. Compare against other U4 series transistors if different voltage or current ratings are needed for the specific circuit design constraints.

Single Bipolar Transistors Part Context

This part belongs to the Microchip Technology discrete semiconductor portfolio, specifically within the bipolar transistor category.
