Overview
The DTC143TEBTL is an NPN digital transistor manufactured by ROHM Semiconductor, housed in a compact SOT-416 (EMT3) surface-mount package. It integrates a single bias resistor (R1) to simplify circuit design. Key electrical specifications include a collector-emitter voltage (VCEO) of 50 V and a continuous collector current (IC) of 100 mA. The device features a typical input resistance of 4.7 kOhms and supports a maximum operating frequency of 250 MHz. Power dissipation is rated at 150 mW, with a minimum DC current gain (hFE) of 100 at 1 mA and 5 V. The component operates within a temperature range of -55°C to +150°C.
Feature Summary
- Integrates a built-in bias resistor to eliminate the need for external input resistors, enabling straightforward inverter circuit configuration.
Applications
- Inverter circuits
- Interface logic
- Driver applications
Procurement Notes
Verify the specific suffix 'B' against official ROHM documentation to confirm pinout compatibility and electrical tolerances, as suffixes often denote tape-and-reel packaging or specific manufacturing lot variations. Ensure the selected variant matches the required thermal and electrical constraints for the target application before finalizing procurement.
Selection Notes
Select this component when a compact NPN digital transistor with a single integrated base resistor is required for space-constrained designs. It serves as a direct replacement for other SOT-416 NPN digital transistors with similar 50V/100mA ratings and 4.7kOhm input resistance, provided the hFE and switching characteristics align with the system requirements.
Part Context
This part belongs to the DTC143 series of digital transistors from ROHM Semiconductor. The series offers various configurations including single-resistor (R1 only) and dual-resistor (R1/R2) options across different packages like SOT-323 and SOT-723. The TE suffix typically indicates a specific tape-and-reel packaging format suitable for automated surface-mount assembly processes.
Replacement Considerations
Compatible substitutes include DTC143TE3 and DTC143EETL, provided the latter's dual-resistor configuration does not conflict with the existing circuit design. Verify that any replacement maintains the same SOT-416 footprint and meets the 50V/100mA electrical limits.
