• High-frequency switching applications

Procurement Notes

Verify the specific ordering code against official Rohm documentation to ensure correct suffix alignment. Confirm that the UMT3 package variant matches the intended PCB footprint. Check current supply status as automotive-grade components may have extended lead times. Ensure storage conditions comply with moisture sensitivity levels defined in the datasheet prior to assembly.

Selection Notes

Select this component when a 30 V NPN transistor with 1 A current capacity is required in a compact SMD form factor. The AEC-Q101 certification makes it suitable for automotive designs where long-term reliability is critical. Consider the 200 mW power dissipation limit for thermal management planning in dense assemblies.

Part Context

This part belongs to the 2SD2656 series of NPN transistors produced by Rohm Semiconductor. The FRAT106 suffix indicates the specific taping quantity and packaging configuration for automated surface-mount assembly. The device utilizes silicon technology optimized for low power consumption and high-speed operation within the small UMT3 footprint.

Replacement Considerations

Consult official substitution guides for pin-compatible alternatives. Verify that any replacement maintains the 30 V VCEO, 1 A IC, and UMT3 package dimensions. Ensure the substitute component also meets AEC-Q101 requirements if used in automotive applications.
