Single Bipolar Transistors Procurement Notes

Verify the ordering suffix TV2 against official ROHM documentation to confirm the specific tape-and-reel packaging format and hFE binning classification. Ensure the procurement channel sources directly from authorized distributors to guarantee component authenticity and traceability. Confirm that the ATV package dimensions match the design requirements before finalizing orders.

Single Bipolar Transistors Selection Notes

Select this component when an 80V PNP transistor with 1A current capability is required. Consider the ATV package constraints regarding thermal dissipation on printed circuit boards. Evaluate the hFE grading options if precise gain control is necessary for the specific application circuit design.

Single Bipolar Transistors Part Context

This part belongs to the 2SB1241 series of power transistors produced by ROHM Semiconductor. It serves as a complement to other NPN counterparts like the 2SD1898. The device is designed for general-use electronic equipment rather than radiation-tolerant or safety-critical automotive applications.

Single Bipolar Transistors Replacement Considerations

The 2SB1260 and 2SB1181 are documented variants within the same datasheet family. Verify pinout compatibility and specific electrical parameter differences before substituting.
