Single Bipolar Transistors Procurement Notes

Verify the specific suffix '-R' against the datasheet to confirm the hFE binning classification (Rank R: 120-240). Ensure the ordering part number includes '-TP' for tape and reel packaging containing 1000 pieces per reel. Confirm halogen-free status if required by checking for the additional '-HF' suffix designation.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with -2A continuous collector current is required in a compact SOT-89 surface-mount footprint. Consider the -50V breakdown voltage limits for circuit design. Evaluate the hFE Rank R specification (120-240) against the base drive requirements of the target application to ensure adequate saturation margins.

Single Bipolar Transistors Part Context

This component belongs to the Micro Commercial Components discrete transistor portfolio, specifically designed for general-purpose amplification and switching tasks. The SOT-89 package provides a balance between thermal dissipation capabilities and board space efficiency compared to smaller packages like SOT-23.

Single Bipolar Transistors Replacement Considerations

Cross-reference with other PNP transistors in the SOT-89 package offering similar -2A current ratings and -50V voltage specifications. Verify pinout compatibility and thermal resistance characteristics before substitution.
