Single Bipolar Transistors Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with ROHM Semiconductor or authorized distributors before integration. Confirm that the SC-70 package dimensions align with your PCB layout constraints. Ensure thermal management strategies account for the specified power dissipation limits under actual operating conditions.

Single Bipolar Transistors Selection Notes

Select this component when a high-current PNP transistor is required in a minimal footprint. The 12 V rating suits low-voltage logic interfaces. Compare against NPN counterparts like the 2SD series for complementary designs. Verify hFE binning requirements if precise gain matching is necessary for the target application performance.

Single Bipolar Transistors Part Context

This part belongs to ROHM's small-signal BJT portfolio, designed for general electronic equipment. The SC-70 package allows for automated surface-mount assembly, supporting high-volume manufacturing. It serves as a standard discrete solution for amplification and switching tasks where space efficiency and moderate current handling are prioritized.

Single Bipolar Transistors Replacement Considerations

Cross-reference with other PNP transistors in the SC-70 package offering similar 1.5 A current ratings and 12 V breakdown voltages. Verify pinout compatibility and thermal characteristics before substitution.
