Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific ordering suffixes match project requirements. Review the official datasheet for handling precautions and storage conditions to ensure long-term reliability.
Selection Notes
Select this component when a single NPN configuration with integrated biasing is required. Ensure the 100 kOhm input resistance aligns with drive source capabilities. Verify that the SOT-23-3 package dimensions fit the available PCB footprint and thermal management constraints.
Part Context
This part belongs to the ROHM DTx series of digital transistors. It serves as a pre-biased solution replacing discrete resistor-transistor combinations. The DTC115ECA designation indicates the base model with specific internal resistor values.
Replacement Considerations
DTC115ECA is listed as a part number alias. Verify pinout compatibility and electrical specifications before substituting with other NPN digital transistors from different manufacturers.
