Overview
The DTC114TKAT146 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SMT3 (SOT-23) surface-mount package. It integrates a bias resistor network with a typical input resistance of 10 kOhms and a typical resistance ratio of 1. The device supports a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. Key electrical parameters include a minimum DC current gain (hFE) of 100 at 1 mA and 5 V, a transition frequency of 250 MHz, and a maximum power dissipation of 200 mW. The unit weight is approximately 5 mg.
Feature Summary
- Integrates built-in bias resistors to simplify circuit design by eliminating external components.
- Provides high-speed switching capabilities suitable for digital logic applications.
- Offers compact surface-mount packaging for space-constrained designs.
Applications
- Digital logic interface circuits
- Switching applications in consumer electronics
- General-purpose signal inversion
Procurement Notes
Verify the specific suffix 'T146' to confirm the tape-and-reel packaging format and quantity per reel. Ensure compatibility with standard SMT3 footprint dimensions during PCB layout. Confirm RoHS compliance status through official manufacturer documentation prior to integration into regulated products.
Selection Notes
Select this component when a single NPN digital transistor with 100 mA current capacity and 50 V voltage rating is required. The integrated 10 kOhm input resistor simplifies drive circuitry. Consider the SMT3 package size for board space limitations. Verify thermal management requirements against the 200 mW power dissipation limit under operating conditions.
Part Context
This part belongs to the DTC114 series of digital transistors from ROHM Semiconductor. The series offers various configurations with different resistor values and packages. The DTC114TKAT146 specifically denotes the NPN polarity, 10 kOhm input resistance, and SMT3 packaging variant within this product line.
Replacement Considerations
Direct substitutes may include other NPN digital transistors with similar 100 mA/50 V ratings and SOT-23 packages, such as those from ON Semiconductor or Diodes Inc., provided pinout and electrical characteristics match. Verify equivalent hFE and switching speeds before substitution.
