Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix TB-E-SY against the official Sanyo delivery specification document to ensure exact component matching. Confirm RoHS compliance status directly with the manufacturer or authorized distributor prior to procurement. Ensure the bulk packaging format aligns with your assembly line requirements. Cross-reference the part number with the latest datasheet revision to confirm no design changes have occurred since the last production run.

Single Bipolar Transistors Selection Notes

Select this component when designing circuits requiring high hFE at low frequencies with minimal input capacitance. The small cob value of 1.5pF makes it suitable for applications where signal integrity is critical. Consider the physical package dimensions during layout planning to ensure adequate spacing and thermal management. This transistor is appropriate for general-purpose amplification rather than high-power switching applications.
