Single Bipolar Transistors Procurement Notes

Verify the manufacturer designation carefully, as the 2SC4003 series was originally developed by Sanyo. Current production may be attributed to onsemi or Rochester Electronics depending on inventory sources. Confirm that the specific suffix matches the required electrical tolerances and packaging style before finalizing procurement orders.

Single Bipolar Transistors Selection Notes

Select this component when a compact NPN transistor with a 400V rating is required for low-current applications. The TO-251 package offers a balance between power dissipation and board space constraints. Ensure the application current remains within the 0.2A limit and that the thermal environment supports the specified maximum junction temperature.

Single Bipolar Transistors Part Context

This part belongs to the 2SC4003 family of NPN power transistors. The series is characterized by high voltage and large current capacity, often utilizing advanced processes like FBET or MBIT for ultrahigh-speed switching. The 2SC4003E-TL-E variant specifically denotes the standard configuration within this lineup.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include other NPN transistors rated for 400V and approximately 0.2A in TO-251 packages. Verify pinout compatibility, particularly regarding the collector connection to the tab, to ensure correct circuit integration without modification.
