Overview
The DTC124XE-TP is an NPN digital transistor manufactured by Micro Commercial Components (MCC). It integrates a single internal base resistor (R1) of 22 kOhms within a compact SOT-523 surface-mount package. The device supports a maximum collector current (Ic) of 100 mA and a collector-emitter breakdown voltage (Vceo) of 50 V. Key electrical specifications include a minimum DC current gain (hFE) of 68 at 5 mA and 5 V, a maximum saturation voltage of 300 mV at 500 µA base current and 10 mA collector current, and a transition frequency of 200 MHz. Power dissipation is rated at 150 mW.
Feature Summary
- Integrates a 22 kOhm bias resistor to simplify circuit design
- Provides high-speed switching with a 200 MHz transition frequency
- Offers low saturation voltage for efficient power handling
Applications
- General-purpose inverter circuits
- Driver circuits for logic interfaces
- Switching applications in consumer electronics
Procurement Notes
Verify the specific suffix 'TP' against the manufacturer's datasheet to confirm packaging details such as reel size or tape width. Ensure that the SOT-523 footprint matches the target PCB layout. Confirm RoHS compliance status through official documentation prior to finalizing procurement orders.
Selection Notes
Select this component when a single-resistor NPN configuration is required. Compare the 22 kOhm input resistance against other series variants if different drive currents are needed. Verify that the 100 mA continuous current rating meets the load requirements and that the SOT-523 package fits the available board space constraints.
Part Context
This part belongs to the DTC124XE series of pre-biased transistors from MCC. It serves as a simplified alternative to discrete BJT setups by combining the transistor and bias resistor into one package. The XE designation typically indicates the specific internal resistor ratio and package type within the broader product family.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Cross-reference with other manufacturers offering NPN digital transistors in SOT-523 packages with similar 22 kOhm base resistance and 50 V ratings.
