Overview
The DTC123JUA-HF is an NPN digital transistor manufactured by Comchip Technology, featuring built-in bias resistors to simplify circuit design. It operates with a collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device incorporates a 2.2 kΩ input resistor (R1) and a 47 kΩ emitter-base resistor (R2). Packaged in the SOT-323 surface-mount format, it supports a power dissipation of 200 mW and functions within a temperature range of -55°C to +150°C.
Feature Summary
- Integrates internal biasing resistors to enable direct logic interfacing without external components.
- Provides simplified switching functionality for inverter circuits through standardized resistance ratios.
Applications
- Logic level shifting between microcontrollers and peripheral devices
- Switching applications in portable electronic equipment
- General-purpose digital signal buffering
Procurement Notes
Verify the specific manufacturer designation when sourcing this component, as the part number structure may appear across different suppliers. Confirm RoHS compliance status directly with the vendor documentation. Ensure the package code matches the required footprint for your PCB layout. Cross-reference the datasheet revision to confirm electrical characteristics align with your design specifications before finalizing procurement.
Selection Notes
Select this component when a compact NPN solution with integrated base and emitter resistors is required. The 2.2 kΩ input resistance suits standard logic families. Verify that the 50 V rating meets the system voltage requirements. Consider the SOT-323 package dimensions against available board space. Compare thermal performance if high-duty cycle operation is anticipated.
Part Context
This component belongs to the family of resistor-equipped transistors designed to replace discrete resistor-transistor networks. It consolidates multiple passive and active elements into a single semiconductor package. This integration reduces component count and assembly time in digital switching applications.
Replacement Considerations
The DTC123JU3 serves as a confirmed substitute with identical pinout and electrical specifications. Both parts utilize the same SOT-323 package and share the 50 V, 100 mA ratings. Verify compatibility with existing PCB footprints before substitution.
