Single Bipolar Transistors Procurement Notes

Verify the specific suffix D3 indicates the hFE bin range of 300-400 as defined in the ordering information table. Confirm the TP suffix corresponds to tape and reel packaging containing 1K pieces per reel. Ensure the component matches the SOT-89 physical dimensions provided in the datasheet specifications.

Single Bipolar Transistors Selection Notes

Select this part when a PNP transistor with -1.5 A continuous collector current is required in a compact SOT-89 footprint. Consider the -25 V collector-emitter voltage limit for low-voltage circuit designs. Evaluate the thermal resistance of 250 °C/W against your heat dissipation requirements to ensure operation within the specified junction temperature range.

Single Bipolar Transistors Part Context

This component belongs to the PXT8550 series manufactured by Micro Commercial Components. The series includes variants distinguished by their DC current gain classification. The D3 designation specifically identifies the highest gain bin within this product family, offering a minimum gain of 300 under specified test conditions.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include other PXT8550 variants such as PXT8550-B, PXT8550-C, or PXT8550-D if lower gain thresholds are acceptable. Verify that any replacement maintains the SOT-89 package and meets the -1.5 A current and -25 V voltage ratings.
