Overview
The DTC123JEBTL is an NPN digital transistor manufactured by Rohm Semiconductor, featuring built-in biasing resistors to simplify circuit design. It operates with a collector-emitter voltage of 50 V and a maximum collector current of 100 mA. The device includes an input resistance (R1) of 2.2 kΩ and an emitter-base resistance (R2) of 47 kΩ. Key electrical characteristics include a DC current gain (hFE) of at least 80 at 10 mA and 5 V, and a transition frequency of 250 MHz. Power dissipation is rated at 150 mW. It is housed in the EMT3F (SOT-416FL) surface-mount package.
Feature Summary
- Built-in bias resistors enable inverter circuit configuration without external input components.
- NPN polarity with pre-biased structure for simplified on/off control.
- Surface mount construction suitable for automated assembly processes.
Applications
- General-purpose switching applications
- Driver circuits for relays and solenoids
- Logic level translation interfaces
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct packaging and tape specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as these details are subject to change based on production schedules and regional availability.
Selection Notes
Select this component when an NPN digital transistor with R1=2.2kΩ and R2=47kΩ is required in an EMT3F package. Ensure the application voltage does not exceed 50 V and current remains within 100 mA limits. Consider thermal management for power dissipation up to 150 mW in enclosed designs.
Part Context
This part belongs to the DTC123 series of digital transistors from Rohm Semiconductor. It is designed as a standard-level product intended for general electronic equipment. The manufacturer explicitly states that this product is not recommended for use in automotive devices unless specified otherwise in a dedicated automotive-grade variant.
Replacement Considerations
The DTC123JE3HZG is listed as a similar specification replacement option. Verify pinout compatibility and package dimensions before substitution. Other variants in the DTC123 family may have different resistor values or packages.
