Single Bipolar Transistors Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with ROHM Semiconductor before procurement. Confirm that the SOT-346 package dimensions match the target PCB footprint requirements. Ensure the component meets all environmental and export control classifications required for the intended manufacturing region.

Single Bipolar Transistors Selection Notes

Select this component when a compact NPN transistor with moderate current handling and high gain is required. The 30V rating limits suitability for higher voltage environments. Consider thermal management constraints due to the small package size and power dissipation characteristics inherent to the SMT3 form factor.
