Procurement Notes

Verify the specific suffix T106 against official ROHM documentation to confirm packaging details and compliance status. Ensure compatibility with standard SMT reflow profiles for the SOT-323 package. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before procurement.

Selection Notes

Select this component when a single NPN digital transistor with a 22 kOhm base resistor is required in a space-constrained SOT-323 footprint. Consider the 100 mA collector current limit and 200 mW power dissipation for thermal management. Verify that the 250 MHz transition frequency meets the signal integrity requirements of the target application.

Part Context

This part belongs to the ROHM DTC series of bias resistor built-in transistors. The TU3 designation indicates the SOT-323 package type, while the '124' identifier typically corresponds to specific internal resistor values and NPN polarity within the family. It serves as a compact alternative to discrete resistor-transistor networks.
