Overview
The DTA143ZETL is a pre-biased NPN digital transistor manufactured by ROHM Semiconductor. It integrates biasing resistors within an EMT3 (SOT-416) surface-mount package to simplify circuit design. Key electrical specifications include a collector-emitter voltage of 50 V, a continuous collector current of 100 mA, and a power dissipation rating of 150 mW. The device features a typical input resistance (R1) of 4.7 kOhms and an emitter-base resistance (R2) of 47 kOhms. It offers a DC current gain (hFE) of at least 80 at 10 mA and 5 V, with a transition frequency of 250 MHz.
Feature Summary
- Integrates built-in biasing resistors to eliminate the need for external input components in inverter circuits.
- Provides simplified on/off control logic by requiring only input signal setting for operation.
- Utilizes a compact SMD/SMT EMT3 package suitable for space-constrained applications.
Applications
- Inverter circuits utilizing built-in biasing resistors
- General-purpose switching applications
- Logic interface circuits
Procurement Notes
Verify the specific ordering suffix to confirm the packaging format, as options include Reel, Cut Tape, and MouseReel configurations. Confirm RoHS compliance status through official documentation before procurement. Ensure the selected variant matches the required supply chain channel and minimum packing quantities defined by the manufacturer.
Selection Notes
Select this component when an NPN configuration with integrated biasing is required for standard switching tasks. Compare against the complementary PNP type, DTA143ZE series, if opposite polarity is needed. Verify that the 50 V breakdown voltage and 100 mA current capacity meet the specific load requirements of the target application circuit.
Part Context
This part belongs to the DTC143ZE series of digital transistors from ROHM Semiconductor. It serves as the NPN counterpart to the DTA143ZE series. The device is designed for general-purpose use rather than automotive-grade environments, distinguishing it from the AEC-Q101 qualified variants in the same family.
Replacement Considerations
The DTA143ZE series is the direct complementary PNP substitute. For equivalent NPN performance in different packages, consider other members of the DTC143ZE family or similar pre-biased transistors with matching R1/R2 ratios and voltage ratings.
