Single Bipolar Transistors Procurement Notes

Verify the exact ordering code against the manufacturer's official documentation before procurement. Confirm that the SPT package variant matches your PCB footprint requirements. Ensure compliance with RoHS standards if applicable to your manufacturing process. Check for any specific automotive or radiation tolerance disclaimers in the latest datasheet revision.

Single Bipolar Transistors Selection Notes

Select this component for circuits requiring moderate current switching with low saturation voltage. Consider the 0.3W power dissipation limit when designing thermal management solutions. Verify that the required hFE range fits within the 120 to 390 specification for your specific biasing needs. Ensure the 50V breakdown voltage exceeds the maximum circuit voltage.

Single Bipolar Transistors Part Context

This part belongs to ROHM's medium power transistor series, designed for general-purpose use. It is distinct from automotive-grade variants which may carry different reliability certifications. The SPT package provides a compact form factor for surface-mount applications. It serves as a standard solution for consumer electronics rather than high-reliability industrial systems.

Single Bipolar Transistors Replacement Considerations

Consult the manufacturer's cross-reference guide for verified substitutes. Ensure replacement parts match the 50V/0.5A ratings and SPT package dimensions. Verify equivalent hFE ranges and saturation voltages to maintain circuit performance.
